As you remember, we've seen crashes in the native code, until we
disabled one of the passes in libgccjit.  So it isn't unthinkable that
some similar problem which we didn't yet see exists, especially in
earlier versions of libgccjit.

Btw, I'm somewhat disappointed by the (lack of) responsiveness from
libgccjit developers: a bug I reported to Bugzilla a week ago (and
which was actually known to them for a month before that, from our
correspondence) didn't get even a single response yet.
