--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-13 branch has been updated by Gaius Mulley <ga...@gcc.gnu.org>: https://gcc.gnu.org/g:2286745b12070320c8dcc5c75d76dd184cb7645e commit r13-7616-g2286745b12070320c8dcc5c75d76dd184cb7645e Author: Gaius Mulley <gaiusm...@gmail.com> Date: Thu Jul 27 22:11:26 2023 +0100 PR modula2/109586 cc1gm2 ICE when compiling large source files. The function m2block_RememberConstant calls m2tree_IsAConstant. However IsAConstant does not recognise TREE_CODE(t) == CONSTRUCTOR as a constant. Without this patch CONSTRUCTOR contants are garbage collected (and not preserved) resulting in a corrupt tree and crash. gcc/m2/ChangeLog: PR modula2/109586 * gm2-gcc/m2tree.cc (m2tree_IsAConstant): Add (TREE_CODE (t) == CONSTRUCTOR) to expression.
