Hello everyone!

I am currently trying to run a GDE model using the latest version of GALPROP i.e. v57. You can find the galdef file attached to this post. When the parameter bremms is set to 1, then the GALPROP code returns the following segmentation fault error in the output file:

But when I turn off the bremms production (i.e. bremms = 0), the simulation runs without any error (as you can see here)

I am running the code in a HPC facility, where I have set the
mem-per-cpu = 8 GBs
(so there's a very little chance of any memory allocation issue). Everything is perfectly installed. Can someone please help me out in solving this error? By seeing the output it seems something is wrong at line no 970 of the file- But I am not sure how to deal with it.

Okay for some reason
skymap_format = 0 (fits format)
doesn't works in v57 properly. It works with v57 by setting skymap_format to other formats.
