Details:

`gal_checkset_automatic_output' plays an important role in setting the output
file name of most utilities: it will remove an existing suffix and add the
utility-specific suffix. It is called when the user doesn't specify any
output.

As described in the comments, this function is suppose to add a suffix is one
doesn't exist. However, during my work, I noticed this is not the case: if
there is no suffix in the input, there will be no suffix in the output
either.

The problem was that the function will write over the space allocated by
`gal_checkset_malloc_cat', with an `strcpy' call immediately before the suffix
searching loop. I am working on the fix now.
