[mpich-discuss] Core dump in parse_args

[kumar.tarun at siemens.com]

Thanks Rajeev for your reply.
I don’t have the exact number as of now. It’s definitely more than 1000. Is there a hard coded limit?

Hi,
     I recently encountered this crash where mpiexec when executed from a bash script and with a large number of arguments crashes. The core dump is as follows:

#0  0x0000000000408ec3 in parse_args ()
#1  0x0000000000409f26 in HYD_uii_mpx_get_parameters ()
#2  0x000000000040397a in main ()

If I reduce the number of arguments then I don’t see the crash. Is it a known issue?

Regards
Tarun
