--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> --- fuzzing source is going to turn up a lot of error-recovery cases - while somewhat interesting they will inevitably be very low priority since GCC has mechanisms to present the user with a nicer error message in such case for production builds. So yes, they are interesting - they would be even more interesting if you provide fixes alongside with the bugreports ;) (you can search bugzilla for ice-on-invalid-code + error-recovery) More interesting are ICEs that do not report an error before.
