That's where I've found ElectricFence to be useful (relative to gdb).
gdb won't notice that the application is dead until it staggers on
for a while and falls down.  ElectricFence can often make the application
stop when it first corrupts memory.  (But ElectricFence changes the
behavior of the application as well).

I've had reasonly good use from valgrind, which changes the behavior
less, but occasionally run into something that confuses it.  So it's
good to have several different tools to try.
