Jeff,
Can you disassemble this function (from gdb) and post the assembly
code ? This might help us to see what's wrong there.
Thanks,
george.

Ricardo was generous to give me access to two configurations with the

1. 64 bit EMT64 desktop / server
2. 32 bit centrino-based laptop
On the 64 bit platform, both the 32 bit and 64 bit intel compilers
worked fine with Open MPI.
On the 32 bit platform, I was able to replicate the problem with a
trivial Open MPI application (even when I configured Open MPI --
without-memory-manager): mpicc segv's about 5 lines into the program
when it executes the following statement in opal/runtime/
opal_init.c:opal_util_init():
if( ++opal_util_initialized != 1 ) {
This makes no sense; there is no reason there should be a segv on
this line. opal_util_initialized is a global variable instantiated
in that file; it is not on the heap.
My gut feeling is that this is a compiler bug. I unfortunately do
not have the time to track this down any further.

Can you be a bit more specific than "it dies"? Are you talking
about
mpif90/mpif77, or your app?
Sorry, tuspid me. When executing mpif90 or mpif77 I have a
segfault and it
doesn't compile. I've tried both with or without input (i.e.,
giving it
something to compile or just executing it expecting to see the
normal "no
files given" kind of message). The intel suite compiled openmpi
without
problems.
Hello,
I've the same problem: when I try to run any mpi-command (like
mpicc, mpirun,
ompi_info, ...) I recive a "Segmentation Fault". I've tried both
openMPI version
1.2.3 and version 1.2.4b0, but all I get is:
$ ompi_info --all
Segmentation fault
Some info on my system:
- GNU/Linux, 2.6.22 Kernel, Slackware 12.0
- Genuine Intel(R) CPU, T2400 @ 1.83GHz GenuineIntel (Toshiba
A-100 Laptop)
- Intel C Compiler 9.1.047
- Intel Fortran Compiler 9.1.041
The configure script options I've used are:
--prefix=/usr CC=icc CXX=icpc F77=ifort FC=ifort
If you need more info just tell me.
Thank you for you attention.
Andrea
