retitle -1 libopenmpi-dev: mpicc segfaults under fakeroot
block 531419 by -1
thanks
Okay, it looks like the root cause is something that's appeared recently in
openmpi - it fails under 1.3.2-2, but works under 1.3-2. Manuel, I'm cloning
the bug for tracking purposes, but I'm certainly not sure that it's actually an
OpenMPI bug at heart. Have you seen anything else like this?
% echo "int main(void) { return 0; }" > test.c
% mpicc.openmpi test.c ; echo $?
0
% fakeroot mpicc.openmpi test.c ; echo $?
Segmentation fault
139
No failures with the other MPI implementations, nor with OpenMPI 1.3. I can
put it under gdb but am missing some debugging libraries in the middle:
% fakeroot gdb mpicc.openmpi
[...]
(gdb) run test.c

I confess that the peculiar interactions of compilers, fakeroot, and (e)glibc
put me well out of my depth.
