When a Stack Overflow occured the new prompt of the REPL becomes fragile
an sometimes crashes on invalid inputs.
A reliant way to make the REPL abort, is by triggering a stack overflow
twice.
Affected Version: 2.0.13
Way to reproduce:
scheme@(guile-user)> (define x (lambda () (x) (x))) ;;; define a
function provoking a stack-overflow
scheme@(guile-user)> (x) (x) ;;; first call of
this function is caught but second aborts the REPL
<unnamed port>:2:0: In procedure x:
<unnamed port>:2:0: Throw to key `vm-error' with args `(vm-run "VM:
Stack overflow" ())'.
Entering a new prompt. Type `,bt' for a backtrace or `,q' to continue.
[1] 13794 abort (core dumped) guile

Yeah this one is gnarly. We couldn't fix it in the 2.0 for various
reasons but addressed it comprehensively in 2.2:

Closing as done. 2.2.0 should be out within a month or two.
