[opensuse-factory] What changed between Build1005 and Build1010 in x86_64?
Hi, I was looking into https://bugzilla.novell.com/show_bug.cgi?id=307781 - basically, Nautilus crashes inside libeel in x86_64 at the start of a varargs function. JPR helped me take disassemblies of both builds; this is the start of the function for both versions: Build1005 - crashes (built on bach.suse.de) (gdb) disassemble eel_canvas_item_new 0x0000000000033c60 <eel_canvas_item_new+0>: mov %rbp,-0x18(%rsp) 0x0000000000033c65 <eel_canvas_item_new+5>: mov %r12,-0x10(%rsp) 0x0000000000033c6a <eel_canvas_item_new+10>: mov %rdi,%rbp 0x0000000000033c6d <eel_canvas_item_new+13>: mov %r13,-0x8(%rsp) 0x0000000000033c72 <eel_canvas_item_new+18>: mov %rbx,-0x20(%rsp) 0x0000000000033c77 <eel_canvas_item_new+23>: sub $0xf8,%rsp 0x0000000000033c7e <eel_canvas_item_new+30>: mov %rcx,0x38(%rsp) 0x0000000000033c83 <eel_canvas_item_new+35>: movzbl %al,%ecx 0x0000000000033c86 <eel_canvas_item_new+38>: mov %r8,0x40(%rsp) 0x0000000000033c8b <eel_canvas_item_new+43>: lea 0x0(,%rcx,4),%rax 0x0000000000033c93 <eel_canvas_item_new+51>: lea 0x20(%rip),%rcx # 0x33cba <eel_canvas_item_new+90> ^^^^ note the offset 0x0000000000033c9a <eel_canvas_item_new+58>: mov %r9,0x48(%rsp) 0x0000000000033c9f <eel_canvas_item_new+63>: mov %rsi,%r12 0x0000000000033ca2 <eel_canvas_item_new+66>: mov %rdx,%r13 0x0000000000033ca5 <eel_canvas_item_new+69>: sub %rax,%rcx 0x0000000000033ca8 <eel_canvas_item_new+72>: lea 0xcf(%rsp),%rax 0x0000000000033cb0 <eel_canvas_item_new+80>: jmpq *%rcx 0x0000000000033cb2 <eel_canvas_item_new+82>: movaps %xmm7,-0xf(%rax) 0x0000000000033cb6 <eel_canvas_item_new+86>: movaps %xmm6,-0x1f(%rax) ^^^^^ note how only xmm7 and xmm6 get used 0x0000000000033cba <eel_canvas_item_new+90>: callq 0x23cd8 <eel_canvas_group_get_type@plt> Build1010 - doesn't crash (built on roth.suse.de) (gdb) disassemble eel_canvas_item_new 0x00002b91e8ee8ee0 <eel_canvas_item_new+0>: mov %rbp,-0x18(%rsp) 0x00002b91e8ee8ee5 <eel_canvas_item_new+5>: mov %r12,-0x10(%rsp) 0x00002b91e8ee8eea <eel_canvas_item_new+10>: mov %rdi,%rbp 0x00002b91e8ee8eed <eel_canvas_item_new+13>: mov %r13,-0x8(%rsp) 0x00002b91e8ee8ef2 <eel_canvas_item_new+18>: mov %rbx,-0x20(%rsp) 0x00002b91e8ee8ef7 <eel_canvas_item_new+23>: sub $0xf8,%rsp 0x00002b91e8ee8efe <eel_canvas_item_new+30>: mov %rcx,0x38(%rsp) 0x00002b91e8ee8f03 <eel_canvas_item_new+35>: movzbl %al,%ecx 0x00002b91e8ee8f06 <eel_canvas_item_new+38>: mov %r8,0x40(%rsp) 0x00002b91e8ee8f0b <eel_canvas_item_new+43>: lea 0x0(,%rcx,4),%rax 0x00002b91e8ee8f13 <eel_canvas_item_new+51>: lea 0x38(%rip),%rcx # 0x2b91e8ee8f52 <eel_canvas_item_new+114> ^^^^^^^^^^ different offset 0x00002b91e8ee8f1a <eel_canvas_item_new+58>: mov %r9,0x48(%rsp) 0x00002b91e8ee8f1f <eel_canvas_item_new+63>: mov %rsi,%r12 0x00002b91e8ee8f22 <eel_canvas_item_new+66>: mov %rdx,%r13 0x00002b91e8ee8f25 <eel_canvas_item_new+69>: sub %rax,%rcx 0x00002b91e8ee8f28 <eel_canvas_item_new+72>: lea 0xcf(%rsp),%rax 0x00002b91e8ee8f30 <eel_canvas_item_new+80>: jmpq *%rcx 0x00002b91e8ee8f32 <eel_canvas_item_new+82>: movaps %xmm7,-0xf(%rax) 0x00002b91e8ee8f36 <eel_canvas_item_new+86>: movaps %xmm6,-0x1f(%rax) 0x00002b91e8ee8f3a <eel_canvas_item_new+90>: movaps %xmm5,-0x2f(%rax) 0x00002b91e8ee8f3e <eel_canvas_item_new+94>: movaps %xmm4,-0x3f(%rax) 0x00002b91e8ee8f42 <eel_canvas_item_new+98>: movaps %xmm3,-0x4f(%rax) 0x00002b91e8ee8f46 <eel_canvas_item_new+102>: movaps %xmm2,-0x5f(%rax) 0x00002b91e8ee8f4a <eel_canvas_item_new+106>: movaps %xmm1,-0x6f(%rax) 0x00002b91e8ee8f4e <eel_canvas_item_new+110>: movaps %xmm0,-0x7f(%rax) ^^^^^ xmm7 to xmm0 get used 0x00002b91e8ee8f52 <eel_canvas_item_new+114>: callq 0x2b91e8ed8c58 <eel_canvas_group_get_type@plt> I'm wondering what might have changed. The bug has been there since Beta1, but with the latest (post-Beta3) it doesn't happen. Did the compiler change or something? The build hosts are different, but shouldn't they produce the same results?

Bah, I'm an idiot. The bug was introduced in Beta3. Ignore the "Beta1" part above :) Federico --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
To check what has changed, you can check the opensuse-commit list: http://lists.opensuse.org/opensuse-commit/2007-09/date.html It will show you all changes by date. The compiler has not been changed past Beta3, Andreas -- Andreas Jaeger, Director Platform / openSUSE, aj@suse.de SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nürnberg) Maxfeldstr. 5, 90409 Nürnberg, Germany GPG fingerprint = 93A3 365E CE47 B889 DF7F FED1 389A 563C C272 A126

The other thing is that there was a rev change (from 3 to 4) with no source change. Did we intentionally bump everything before RC1? -JP -- JP Rosevear <jpr@novell.com> Novell, Inc. --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

You mean release? Rebuilds always increment the Release tag by 1 in factory and by .1 in released products. Henne -- Henne Vogelsang, openSUSE.

Only if the rpms can reach customers, like the FACTORY rpms do.

You mean a change of the build number? We increase it always when we rebuild and one of the packages it depends on has been changed. JP, you were once complaining that after a rebuild the number was not increased even if it contained different dependencies - now it is really increased ;-) Andreas -- Andreas Jaeger, Director Platform / openSUSE, aj@suse.de SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nürnberg) Maxfeldstr. 5, 90409 Nürnberg, Germany GPG fingerprint = 93A3 365E CE47 B889 DF7F FED1 389A 563C C272 A126

Yes, I'm glad. I just didn't realize it was now working that way. -JP -- JP Rosevear <jpr@novell.com> Novell, Inc. --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
