Gnuastro 0.3.23 fails on big-endian systems in the Debian builds (you can click on the red "Build attempted" signs to see the log of the whole build. This is the error:

The function code in `mkprofcat2.txt' is `1', not `0' (as the error message says).

I was able to track down the problem: we are treating the function codes as an 8-bit integers in some places, and 32-bit integers in others. Since there is only 6 profiles currently (profile codes between 1 and 7), only the smallest byte was only necessary.

On little-endian systems (most commonly used systems including mine), the smallest byte is placed first, so reading a 32-bit integer as an 8-bit integer worked successfully and there was no problem. But on big-endian systems, only the last byte is filled and so the first byte will be read as 0.

I am busy fixing this now.
