Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jkratoch at gcc dot gnu.org, | |tromey at gcc dot gnu.org --- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Works also with -O1 -fsanitize=address -g or -O0 -fsanitize=address -g --param asan-use-after-return=0. My guess is that for -O0 gdb has some code to detect function prologues/epilogues and get's upset by the conditionals in use-after-return prologue (or epilogue?) instrumentation. CCing some GDB folks to find out if it isn't just a GDB bug, or what exactly would they like to see from GCC in this case, so that they can handle it.
