hi, the following program has a stack array overran and static arrary overran . overran of this kind may be a very hard to find bug in a software .so can gcc provide extra information for other debugging tools to check if an array is overran ? program.c: int static[5]; int main(void) { int stack[5]; static[5] = 0; stack [5] = 0; return 0; } i have no idea about whom to ask ,gdb or gcc or both ??
