--- Comment #7 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Martin Jambor <jamb...@gcc.gnu.org>: https://gcc.gnu.org/g:b3f60112edcb85b459e60f66c44a55138b1cef49 commit r12-5630-gb3f60112edcb85b459e60f66c44a55138b1cef49 Author: Martin Jambor <mjam...@suse.cz> Date: Tue Nov 30 15:35:18 2021 +0100 ipa-param-manip: Be careful about a reallocating hash_map PR 103449 revealed that when I was storing result of one hash_map lookup into another entry in the hash_map, I was still accessing the entry in the table, which meanwhile could get reallocated, making the accesses invalid-after-free. Fixed with the following, which also simplifies the return statement which must have been true even now. gcc/ChangeLog: 2021-11-29 Martin Liska <mli...@suse.cz> Martin Jambor <mjam...@suse.cz> PR ipa/103449 * ipa-param-manipulation.c (ipa_param_body_adjustments::prepare_debug_expressions): Be careful about hash_map reallocating itself. Simpify a return which always returns true.
