[moving over to guile-devel...]

Not to disagree with anything that's already been said in this
thread...  But I wonder if there is a way to make Guile's stack
overflow checking a bit less fragile - i.e. less subject to the
behaviour of particular compilers / OSs / optimization options?

I think all we're really trying to do, with the stack overflow
feature, is guard against a suspected infinite recursion, without
resorting to crashing the whole program.  Perhaps there is a cunning
way to do that without having to set an arbitrary stack depth limit?
Any ideas would be most welcome.
