Unfortunately I do not think Comparing between versions in https://gcc.gnu.org/onlinedocs, it appears that -fsanitize-recover is not configurable for folks still with GCC 4.x series, and this patch is not very useful unless you disable the recovery for the purpose of running our tests as you said X-<. > With this patch, all of that happens automatically when you > run: > > make SANITIZE=address test > > Signed-off-by: Jeff King <peff@xxxxxxxx> > --- > Makefile | 4 ++++ > 1 file changed, 4 insertions(+) > > diff --git a/Makefile b/Makefile > index 9c9c42f8f..59f6bdcd7 100644 > --- a/Makefile > +++ b/Makefile > @@ -1012,6 +1012,10 @@ ifdef DEVELOPER > CFLAGS += $(DEVELOPER_CFLAGS) > endif > > +ifdef SANITIZE > +BASIC_CFLAGS += -fsanitize=$(SANITIZE) -fno-sanitize-recover=$(SANITIZE) > +endif > + > ifndef sysconfdir > ifeq ($(prefix),/usr) > sysconfdir = /etc
