Yes, SIGABRT is synchronous for all purposes. So the only danger is
that g_string_free() or g_free() could fail while we're in
g_assert(false). But they don't, which makes sense because they are
totally unrelated to g_assert() and therefore can handle re-entrancy.
If malloc aborts due to a double free or other similar problem, you may
risk reentering it.
