--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Marek Polacek <mpola...@gcc.gnu.org>: https://gcc.gnu.org/g:f84aded848f6fdd2704c9376263c6d1aee6bb0ca commit r10-7568-gf84aded848f6fdd2704c9376263c6d1aee6bb0ca Author: Marek Polacek <pola...@redhat.com> Date: Mon Mar 30 15:49:17 2020 -0400 c++: Fix crash in gimplifier with paren init of aggregates [PR94155] Here we crash in the gimplifier because gimplify_init_ctor_eval doesn't expect null indexes for a constructor: /* ??? Here's to hoping the front end fills in all of the indices, so we don't have to figure out what's missing ourselves. */ gcc_assert (purpose); The indexes weren't filled because we never called reshape_init: for a constructor that represents parenthesized initialization of an aggregate we don't allow brace elision or designated initializers. PR c++/94155 - crash in gimplifier with paren init of aggregates. * init.c (build_vec_init): Fill in indexes. * g++.dg/cpp2a/paren-init22.C: New test.
