Bill,

I guess you might be right.
The only info that I can gather from GDB are the following:

------------------------------------------------------------------------------------------------------------------------

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0xfffb7196430 (LWP 13646)]
0x7c0802a6f821ffd0 in ?? ()
Missing separate debuginfos, use: debuginfo-install glibc-2.12-1.149.el6_6.7.ppc64
(gdb) bt
#0  0x7c0802a6f821ffd0 in ?? ()
#1  0x00000fffb7f6e590 in .start_thread () from /lib64/libpthread.so.0

#2  0x00000fffb7d448ec in .__clone () from /lib64/libc.so.6
-----------------------------------------------------------

Looks like there the problem comes from libthread or glibc. So, could be the init_thread problem you are talking about.
I think some debuginfo are missing, but I don’t have any root access to this machine so I can’t install anything.

Do you have any other idea how to investigate this problem?

Best,
Simone
