--- Comment #2 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:c3d3bb0f03dbd02512ab46979088ee8e22520c24 commit r11-7980-gc3d3bb0f03dbd02512ab46979088ee8e22520c24 Author: Jason Merrill <ja...@redhat.com> Date: Sat Apr 3 16:17:29 2021 -0400 c++: array new initialized from a call [PR99643] Here the get_foo() call results in a TARGET_EXPR, which we strip in massage_init_elt, but then when build_vec_init tries to use it to initialize the array element we crash because build_aggr_init expects a class rvalue to have a TARGET_EXPR. So don't strip it. The stripping was added in r206639 for PR59659, so I checked that removing it didn't significantly increase compile time or memory usage for that testcase; compile time was unaffected, memory usage increased by 0.00004%. gcc/cp/ChangeLog: PR c++/99643 * typeck2.c (massage_init_elt): Don't strip TARGET_EXPR. gcc/testsuite/ChangeLog: PR c++/99643 * g++.dg/cpp0x/initlist-new5.C: New test.
