--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-10 branch has been updated by Iain D Sandoe <ia...@gcc.gnu.org>: https://gcc.gnu.org/g:acd300cfdc434f03f1b08e46bca98b963d43ebc3 commit r10-10798-gacd300cfdc434f03f1b08e46bca98b963d43ebc3 Author: Iain Sandoe <i...@sandoe.co.uk> Date: Sat Aug 14 12:27:55 2021 +0100 Objective-C: fix crash with -fobjc-nilcheck When -fobjc-nilcheck is enabled, messages that result in a struct type should yield a zero-initialized struct when sent to nil. Currently, the frontend crashes when it encounters this situation. This patch fixes the crash by generating the tree for the `{}` initializer.
