The problem was corrected and checked (on a 32-bit and 64-bit little-endian) system. It has been pushed to the main repo.

It will be submitted to Debian to see if it (hopefully) builds correctly on all architectures (except `sh4').

Gnuastro 0.3.31 (fix to bug #51467) was approved and uploaded onto Debian a few hours ago and almost immediately several crashes were reported in the tests (they are still ongoing, but already 12 architectures have failed!):


A summary of the results is:

Except for the `sh4' architecture, the rest are all in MakeProfiles and appear related.

After trying the build on a 32-bit virtual machine, I was able to find the cause of the problem: the `mode' element of the `mkprofparams' (defined in MakeProfile's `main.h') was defined as uint8_t, but in the `ui_parse_coordinate_mode', it was being read as an `int'! Francly it is strange for me why this didn't cause a crash on my own system!?!

This maybe one of the problems with compilers becoming "smarter" (and hiding problems)!
