The lack of a debugger that works reliably with recent gcc versions has led to an increasing backlog of uninvestigated execution failures.



Do you think it's the debugger or the compiler that's at fault?


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.
