If it's crashing in libgccjit that sounds like a libgccjit bug.  Just to
mention, using `comp-libgccjit-reproducer' might be helpful here to
produce a libgccjit only reproducer (assuming it manages to create one
before crashing).

If the reproducer is created I can have a look here to see if that's
reproducible if you like.
