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
