https://bugzilla.novell.com/show_bug.cgi?id=358865 Summary: memory corruption in Xvnc, prevents vnc installation Product: openSUSE 11.0 Version: Alpha 1 Platform: PowerPC OS/Version: Linux Status: NEW Severity: Normal Priority: P5 - None Component: X.Org AssignedTo: sndirsch@novell.com ReportedBy: olh@novell.com QAContact: xorg-maintainer-bugs@forge.provo.novell.com CC: power-bugs@forge.provo.novell.com Found By: --- 11.0a1 and also current factory fails with vnc install. As soon as one connects to the server, the Xvnc process gets terminated by glibc malloc checker. sometimes Xvnc gets aborted right away after connect. sometimes a corrupted screen is displayed, then Xvnc is terminated. A quick test on i386 factory shows that vnc seems to work there. I dont have a better backtrace at the moment, due to lack of related -debuginfo.rpm in the inst-sys. Program received signal SIGABRT, Aborted.

The value of 'height' in gdb is the height at the time of the crash, It should be 0 because of the while loop. I have no idea why it isn't. The malloc checker complains because the header of the malloced area has been overwritten. I don't see right off hand what might have caused this. There are some things you could try: 1. comment out the GetImage() function call. 2. comment out the memcpy() 3. add an ErrorF(">> %p %p %i\n",optr, buf, height); 4. if possible also try buidling with '-O0'. At present I have no good idea on how to exchange things on an inst-sys. I've done this once or twice in the distant past. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

of course, that should have been something like: Xvnc -noreset -geometry 1024x768 -rfbport 5901 -rfbwait 120000 -depth 16 :42

port 5901 doesn't work. There's another VNC already running.

No garbage when connecting from x86_64(vncviewer) to ppc64(Xvnc). Maybe you're using a different VNC viewer?
