Dear Sir,

We are running MPI applications on AIX 5.3 with
64 bit libraries. I'm compiling code with xlc_r, xlC_r and xlf_r and
linking with lc_r,lpthreads_r. But application doesn't enter into main()
itself. Its giving following error:

cmpi@pn02 $ ./hello
Segmentation fault (core dumped)
cmpi@pn02 $ dbx ./hello core
Type 'help' for help.
[using memory image in core]

Segmentation fault in pthread_init at 0x9000000003aed90
0x9000000003aed90 (pthread_init+0x7b0) f8030498        std   r0,0x498(r3)

could you please let me know what this problem is, and  Kindly let us
know how to resolve this problem.

Thanks & Regards,
