--- Comment #2 from Agostino Sarubbo <ago at gentoo dot org> --- (In reply to Mark Wielaard from comment #1) > Note that in some cases elfutils deliberately does unaligned accesses if it > believes it is safe. See the following in lib/eu-config.h: > > /* Define ALLOW_UNALIGNED if the architecture allows operations on > unaligned memory locations. */ > #define SANITIZE_UNDEFINED 1 > #if (defined __i386__ || defined __x86_64__) && ! CHECK_UNDEFINED > # define ALLOW_UNALIGNED 1 > #else > # define ALLOW_UNALIGNED 0 > #endif > > Note that it is to not allow unaligned accesses when configuring with > --enable-sanitize-undefined (which adds -fsanitize=undefined > -fno-sanitize-recover to CFLAGS and CXXFLAGS). > > Are you configuring using --enable-sanitize-undefined? Or adding > -fsanitize=undefined by hand? In the later case you should also add > -DCHECK_UNDEFINED=1 It was added by hand..I need to test if I obtain those warning with --enable-sanitize-undefined -- You are receiving this mail because: You are on the CC list for the bug.
