Please call the variable:

	ptr_command_line

(gnu coding standards don't like edit case variables)

Please write the above as a function cmdline_location() that returns the 
address.

I'd change that to strdup (argv) (freeing the old value if necessary). 
that way the code can't run foul of GDB freeing up the parameter.

Otherwize, approved.
