--- Comment #13 from Iain Sandoe <iains at gcc dot gnu.org> --- (In reply to Eric Gallager from comment #12) > GCJ has been removed from GCC 7. But on the other hand this isn't really so > much a java bug itself as it is an unwinding bug that java just happened to > be the one to tickle. So is it worth keeping this bug open? agreed it's an unwinder bug, I suppose we need a non-Java reproducer. As of Darwin11, nothing should be using the libgcc_s unwinder (and really it shouldn't be used for darwin10). The broken unwinder in the darwin9 libgcc_s can't be easily fixed (44107) - and the resolution there is to update the installed lib. It's possible that we're going to struggle to get a fix unless/until we can make output compatible with the compact unwinder. We can leave this open, but as stated, someone should try to find a non-Java reproducer.
