When a segmentation fault error (or similar opaque errors) are reported, it is really hard to find the cause of the problem on the user's system. The best way is use Valgrind, which gives a very nice report of exactly which function caused the memory failure.

Currently the user has to take these steps:

1. Install Valgrind (available in most package managers).

2. Configure Gnuastro while adding the following options for no shared libraries, with debugging flags, and with no optimization so Valgrind can report the status accurately as shown below:

(This is also described in the manual.)

3. Add `valgrind --leak-check=yes' to the start of the command in the script that produces the memory error.

To facilitate these steps for the user, we can add an option to configure like `--enable-valgrind-checks'. This option will cause `./configure' to check if Valgrind is installed, will add those configure options, and will run all the tests with valgrind appended to the start of the command.

If you can work on this put a comment ;-), I am too busy right now...
