The routine fault is declared in glplib2.c. It is used to terminate
program execution only if the user program passes incorrect parameters
to glpk api routines, i.e. corresponding errors should be thought as
fatal (like segmentation fault, for example). So most elegant way to
prevent crashing is not to pass incorrect parameters to api routines.
Another way is to use the routine lib_set_fault_hook (see comments to
this routine in glplib2.c).
