I have attached the backtrace. Frame #0 is at address 0x0. In frame #1 a jump table is used and the index obviously point to a null pointer.
I've started valgrind to check whether there are heap overflows. I expect a result in one hour.
Valgrind reports no errors that can lead to heap overflows. So there might only be a buffer overflow on the stack.
I suspect that this is related to glibc because with opensuse 11.4 some applications stopped to work because of memcpy. Maybe there is a similar change that causes my crashes.
I do not say that glibc is broken. Maybe it is now stricter than in earlier versions.
If you have a self-contained testcase - best without involving glibc - the glibc maintainer (that's me;) will look at a bugreport via bugzilla.novell.com and tell you what's broken... right now with the information you've given, it's not clear what the problem is. Btw. the memcpy change was not in 11.4, we disabled it, Andreas -- Andreas Jaeger aj@{suse.com,opensuse.org} Twitter/Identica: jaegerandi SUSE LINUX Products GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany GF: Jeff Hawn,Jennifer Guild,Felix Imendörffer,HRB16746 (AG Nürnberg) GPG fingerprint = 93A3 365E CE47 B889 DF7F FED1 389A 563C C272 A126 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
