[Bug fortran/29649] New: Force core dump on runtime library errors

["sfilippone at uniroma2 dot it" <gcc-bugzilla at gcc dot gnu dot org>]

Running an application I got the following error 
Fortran runtime error: Attempt to allocate negative amount of memory.  Possible
integer overflow

This is not very helpful in debugging, as it gives no clue as to where in the
code it occurred. It would be extremely helpful to have a way to force a
backtrace produced, either explicitly via stderr (as Intel Fortran does for
code compiled with -traceback), or implicitly by producing a core dump.

Am not sure whether this should be filed against the front end (i.e.: a compile
time option) or the library (runtime environment variable? )
