[Bug c++/102071] [10/11 Regression] crash when combining -faligned-new=N with array cookie
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=102071 --- Comment #7 from CVS Commits --- The releases/gcc-11 branch has been updated by Jason Merrill : https://gcc.gnu.org/g:394c852a6b4bed8117c790c2cd1553e224975ad5 commit r11-9982-g394c852a6b4bed8117c790c2cd1553e224975ad5 Author: Jason Merrill Date: Sun Mar 27 12:36:13 2022 -0400 c++: low -faligned-new [PR102071] This test ICEd after the constexpr new patch (r10-3661) because alloc_call had a NOP_EXPR around it; fixed by moving the NOP_EXPR to alloc_expr. And the PR pointed out that the size_t cookie might need more alignment, so I fix that as well. PR c++/102071 gcc/cp/ChangeLog: * init.c (build_new_1): Include cookie in alignment. Omit constexpr wrapper from alloc_call. gcc/testsuite/ChangeLog: * g++.dg/cpp1z/aligned-new9.C: New test.

PR c++/102071 gcc/cp/ChangeLog: * init.cc (build_new_1): Check array_p for alignment. gcc/testsuite/ChangeLog: * g++.dg/cpp1z/aligned-new9.C: Add single-object test.
