Hi Niels,

I am using gfortran with gdb, and I would like to set a single break
point that stoppped the program just before it crashed due to any
runtime error. That would allow me a last view at my variables before
a any crash.

I would also like to set a single breakpoint ("break STOP" ??) that
stopped the program whenever the fortran statement named "STOP" were
about to be executed.

The relevant symbols are __gfortran_stop_numeric, __gfortran_stop_string for STOP and __gfortran_runtime_error for runtime errors. It should be possible to set breakpoints on them, though I haven't tried.

Cheers,
- Tobi
