Follow-up Comment #2:

I had a closer look and found the source of the problem, it is now fixed and
has been pushed
<http://git.savannah.gnu.org/cgit/gnuastro.git/commit/?id=6836e7d022afd6e> to
the main repository. From the commit message:

The `data' element of Table's `outcolumn' structure (in `bin/table/main.h')
has a `void *' type to allow various types. However, to allocate space for the
output column we were using the `sizeof' operator on it! This would give a
size of 1 and would cause a crash some systems. 

In the previous commit (5c41564: New function to return the size of FITS
datatype), a new function was added to the Gnuastro FITS functions to return
the number of bytes in each datatype. With that function, the datatype's size
is now also stored in the `outcolumn' structure and the allocation is done
based on that.
