Description Hans-Albert Schneider 2010-03-12 01:59:32 UTC

Created attachment 33987 [details]
Stacktrace

We are using Fontconfig 2.8.0 with Freetype 2.3.11, libxml2 2.7.6, and Qt 4.5.1.
We experience occasional bus errors in our nightly test benches; a stack trace from last night is attached.
The program has been compiled with Sun C++ 5.9 on Solaris 9, for 64bit SPARC.

siginfo.si_code is BUS_OBJERR.

According to what I have read about SIGBUS, this looks to me like some mmap()ed memory is being accessed either out-of-bounds or after munmap().

Are you using NFS on your home?

Comment 2 Hans-Albert Schneider 2012-04-11 13:29:34 UTC

As I have changed jobs meanwhile, I do not have access to the details anymore.
But yes, the home directories were mounted via NFS. I think the NFS server was a Linux machine (some CentOS version, probably).

Comment 3 Hans-Albert Schneider 2012-04-11 13:35:53 UTC

Oh, and I think the NFS clients running Linux did not show the problem.

Comment 4 Akira TAGOH 2012-04-11 18:42:12 UTC

Thanks. this should be duplicate then.
