Summary: TigerVNC crash with SIGPIPE
Initial Comment:
I have only seen this crash when interacting with Motif programs. That may be
because I mostly use Motif programs (CAD tools) or may be something to do with
how Motif behaves.
I am using TigerVNC x86_64 version 1.1.0 on RHEL 4.6:
Linux HOST 2.6.9-67.ELsmp #1 SMP Wed Nov 7 13:56:44 EST 2007 x86_64 x86_64
x86_64 GNU/Linux
Stacktrace
Program received signal SIGPIPE, Broken pipe.

Message:
I am using the build from sourceforge files section. I don't have
LD_ASSUME_KERNEL set. I DO have LD_LIBRARY_PATH set.
Unfortunately, it is not reproducible. What I can I do to get a better
debug dump? Do you have debug symbols available for the binaries?
Alternatively, I can try making a debug build. Is Xvnc simpler to build now
that it is based on the newer Xorg?
ldd shows that only system libraries are used:
ldd Xvnc
libpam.so.0 => /lib64/libpam.so.0 (0x0000003ba5d00000)
libdl.so.2 => /lib64/libdl.so.2 (0x0000003ba4d00000)
librt.so.1 => /lib64/tls/librt.so.1 (0x0000003ba9b00000)
libm.so.6 => /lib64/tls/libm.so.6 (0x0000003ba4b00000)
libc.so.6 => /lib64/tls/libc.so.6 (0x0000003ba4800000)
libpthread.so.0 => /lib64/tls/libpthread.so.0 (0x0000003ba5100000)
libaudit.so.0 => /lib64/libaudit.so.0 (0x0000003ba6300000)
/lib64/ld-linux-x86-64.so.2 (0x0000003ba4400000)

Message:
I don't have access to Laker, but I use IC5141 over vnc daily. Can you
check to make sure that LD_LIBRARY_PATH and LD_ASSUME_KERNEL are NOT set in
the shell that you launched Xvnc from? Also, is this reproducible? If so,
please can give me some steps to reproduce it. Did you build Xvnc from
source?
Thanks,
-brian

Which tools cause this crash? I'm using 1.1 with a variety of different
EDA tools and have never seen this.
