Maybe. However, with `crash' I mean that lilypond aborts with a
segfault or something similar. It's quite easy to write an endless
loop or to exhaust the memory, but in the former case lilypond's guile
interpreter just hangs, and you should be able to abort with ^C, and
in the latter case lilypond should abort with a proper (Guile) error
message, and maybe we can add some measures to prevent unplausible
memory allocations.

AFAIK, this is not possible in Guile since it is an interpreted
language.
