--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Andrew Macleod <amacl...@gcc.gnu.org>: https://gcc.gnu.org/g:ab202b659dbdfd3a1f45ffe7a5052f35b5e8fa6d commit r12-5587-gab202b659dbdfd3a1f45ffe7a5052f35b5e8fa6d Author: Andrew MacLeod <amacl...@redhat.com> Date: Mon Nov 29 19:53:50 2021 -0500 Don't reuse reference after potential resize. When a new def chain is requested, any existing reference may no longer be valid, so just use the object directly. PR tree-optimization/103467 * gimple-range-gori.cc (range_def_chain::register_dependency): Don't use an object reference after a potential resize.
