Bug#1107687: /usr/bin/mpirun.openmpi: Segmentation Fault when starting MPMD programs

[Nils-Arne Dreier]

Package: openmpi-bin
Version: 5.0.7-1
Severity: important
File: /usr/bin/mpirun.openmpi
X-Debbugs-Cc: nils.dreier at posteo.de

Dear Maintainer,

i'm facing a segmentation fault when running MPMD programs with mpirun. This can be reproduced by simply calling

mpirun -n 1 date : -n 1 date

Of course I would expect that the programs are executed instead of the segmentation fault.

I'm running on Ubuntu 25.04 but I can also reproduce this behavior in Debian sid and trixie.

Thanks!
Nils
