The debugger crashes when certain (recently pretty much any) debug 
information is enclosed.
Thus, the debugger is at fault, for crashing.  But for all I know, the 
compiler might also be at
fault, for emitting invalid debug information; however it is more likely 
newer debug information
that my vintage gdb can't understand.

The execution failures are most likely gcc bugs, except when prefetching 
unmapped memory
is involved; the simulator had a bug there.
