1: guard top-of-stack reads
2: widen condition for logging top-of-stack

The issue patch 2 fixes (a curious lack of an intermediate call stack
entry) was observed in practice; patch 1 is a result of me just looking
at the code (and if I have missed some aspect of why this isn't a
problem in reality, that patch could be easily dropped).
