Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ebotcazou at gcc dot gnu.org --- Comment #20 from Jakub Jelinek <jakub at gcc dot gnu.org> --- You can use __builtin_setjmp and __builtin_longjmp in the same function, only if they use a different buffer. Otherwise it is invalid. So, while we shouldn't ICE on invalid code, not sure why you are listing 4 here. CCing Eric for the other __builtin_setjmp related issues.
