And anyway, I'm stepping through the > code of libgccjit, not comp.c, when the crash happens. 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. Andrea
