Yes, every system has characteristic address ranges in which you can
expect various things to be placed. After some time spent in debugger
you can catch clearly invalid references at a glance. Addresses as small
as 0x01 tend to be always invalid on Linux, hence my suspicions it was
heavily stomped on. But David has more clue anyway than I have, as he
knows stuff like stack frames inside out, unlike me :)
