erase() always invalidates the iterator. That means you can't use it any

iteration, so this code is broken.
Is anyone aware of any decent compile-time tools to
detect this kind of error? Preferably one that doesn't
cost a dime per line.
Any halfway modern implementation of the C++ standard library has a
diagnostic mode. This mode sacrifices some performance and some of the
complexity guarantees coming from the STL in order to verify at runtime
that a used iterator is actually used correctly.
If your implementation doesn't have such a diagnostic mode, you might want
to take a look at an alternative implementation. I know that both STLport
and Dinkumware have such a mode and they both can replace the native
standard library of many compilers.
