I'd say it's forgetting to bind stack variables to a delegate literal, leading to subtle crashes later on.

This could be "fixed" by adding a short hash to every stackframe, then comparing that on external variable access (in debug mode). Of course, since 2.0 has effectively obsoleted this problem, there's little point :)
