re PR sanitizer/78832 (-fcompare-debug failure (length) with -fsanitize=address)
PR sanitizer/78832
* sanopt.c (sanitize_asan_mark_unpoison): Remove next variable, use
continue if gsi_next should be skipped.
(sanitize_asan_mark_poison): Remove prev variable, use continue if
gsi_prev should be skipped. When removing ASAN_MARK, do gsi_prev
first and gsi_remove on a previously made copy of the iterator.
* gcc.dg/asan/pr78832.c: New test.
