--- Comment #5 from Arnd Bergmann <arnd at linaro dot org> --- I just tried reproducing the earlier bug with my gcc build and failed to get the ICE, so I assume this is a different problem despite also getting "internal compiler error: in get_substring_ranges_for_loc, at input.c:13xx". I opened https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78569, which is seems related to a buffer overflow in sprintf(), which is similar to the one here, but as far as I can tell, this one doesn't overflow as we print an 'unsigned char' variable into a five-byte string.
