--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:bb2921ab84dba014f24be06663636c7fb1361474 commit r13-221-gbb2921ab84dba014f24be06663636c7fb1361474 Author: Jason Merrill <ja...@redhat.com> Date: Mon May 9 16:03:35 2022 -0400 c++: fix arm-eabi crash building libstdc++ [PR105529] My recent change to cxx_eval_store_expression asserts that the target and value can only end up having different types in the case of an empty base; this was crashing arm-eabi compilers because in that ABI [cd]tors return *this, and weren't converting it to void* first. This also shares the 'return this' code between the three places it occurs. Thanks to Marek for the tests. PR c++/105529 gcc/cp/ChangeLog: * decl.cc (maybe_return_this): Replace... (finish_constructor_body, finish_destructor_body): ...these. (finish_function_body): Call it. * optimize.cc (build_delete_destructor_body): Call it. * cp-tree.h (maybe_return_this): Declare. gcc/testsuite/ChangeLog: * g++.dg/cpp2a/constexpr-dtor13.C: New test. * g++.dg/cpp2a/constexpr-dtor14.C: New test.
