[bug #29574] VM stack overflows aren't properly handled [1.9.10]

[Ludovic Courtès]

Update of bug #29574 (project guile):

             Assigned to:                    None => civodul

Follow-up Comment #1:

The problem stems from the fact that `throw' is now implemented in Scheme, so
it needs VM stack space to run.

I've come up with the following hack: a small VM stack space is reserved and
made available only upon stack overflow, so that `throw' can run to
completion.  (See attached patch.)

An alternative would be create a new VM and switch the current thread's VM
for the dynamic extent of the scm_throw () call.  That seems overkill and
fragile though.

Comments?

Thanks,
Ludo'.
