As a result we add unpoison/poison for it to the gimple. But then sanopt removes the unpoison. So the second time we call the function and want to load from the array asan still considers it poisoned. The following patch fixes it by removing the .ASAN_MARK internal calls during gimple lowering if they refer to TREE_STATIC vars. 2024-02-01 Jakub Jelinek <ja...@redhat.com> Jason Merrill <ja...@redhat.com> PR c++/113531 * gimple-low.cc (lower_stmt): Remove .ASAN_MARK calls on variables which were promoted to TREE_STATIC. * g++.dg/asan/initlist1.C: New test.
