I've just tried the following:

---------------------
A fatal error internal to GDB has been detected, further
debugging is not possible.  GDB will now terminate.

This is a bug, please report it.  For instructions, see:
<https://www.gnu.org/software/gdb/bugs/>.

Segmentation fault (core dumped)

So it might be that GDB is actually busted.

I'll try to recompile from scratch and try again.

Javi.
