In any reasonable compiler this will just lead to a harmless address computation that is then discarded if out-of-bounds, but it's still undefined behaviour and the sanitizer rightly complains. libctf/ChangeLog 2021-03-25 Nick Alcock <nick.alc...@oracle.com> PR libctf/27628 * ctf-lookup.c (isqualifier): Don't dereference out-of-bounds qhash values. -- You are receiving this mail because: You are on the CC list for the bug.
