--- Comment #1 from Mark Wielaard <mark at klomp dot org> ---
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
