--- Comment #10 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-16 branch has been updated by Andrew Pinski <[email protected]>: https://gcc.gnu.org/g:98237ff9aad0ee1ae13dc27d6b3b7c2cc0eb9acd commit r16-9118-g98237ff9aad0ee1ae13dc27d6b3b7c2cc0eb9acd Author: Andrew Pinski <[email protected]> Date: Tue Jun 9 18:12:52 2026 -0700 ipa: Fix lifetime issue with hash_map::put in prepare_debug_expressions [PR125699] Here the code was originally: tree *d = m_dead_ssa_debug_equiv.get (value); m_dead_ssa_debug_equiv.put (dead_ssa, *d); but hash_map::put's 2nd argument is a reference. So if the hashmap decides it needs to resize, the argument is freed. So the fix is simple change the type of d to tree and dereference the get. Since tree is a pointer there is not enough data to care about the extra copy. r12-5630-gb3f60112edcb85 was a similar fix in the same function in fact. Pushed as obvious after a bootstrapped and tested on x86_64-linux-gnu.
