[Linux-ia64] pthread lib setting for ia64?

["Pereira, D LailaX E" <d.lailax.e.pereira@intel.com>]

Hi 
While running my program on a Linux machine (turbo linux) Itanium processor,
the program does a segmentation fault on a pthread_create(..) command. I
checked the arguments of the pthread_create(...) and there is no problem
with them. So I ran the program thru gdb , and got the following on seg
fault:

Starting
program:
/fxsvrux001/home1/depereir/Tmk_SMP-26/apps/test_C/bin.ia64_linux2/stress.udp
-- -n2 -N1 -hcopilot{,} -p5001 -i1
Tmk_startup: SWAPDIR=(null), putting swap file in "/tmp".

Program received signal SIG32, Real-time event 32.
0x2000000000217ba2 in rt_sigsuspend () from /lib/libc.so.6.1

(gdb) 


the program receives a SIG32 signal from rt_sigsuspend(..) .I am unable to
figure this out. 
Is there some setting for pthread library that has to be done before running
on itanium? some patch or something that I am missing?? is there some stack
size to be set??
Please let me know.

thanks
