commit r16-5810-g9dc1f699a879c9078d873d9c12811b864a1f4c33 Author: Nathaniel Shead <[email protected]> Date: Sun Nov 30 14:43:33 2025 +1100 c++/modules: Fix assertion in write_function_def for DECL_LOCAL_DECL_P I hadn't retested r16-5727-g858f3007278337 on trunk before pushing and I'd missed that it interacts badly with the assertion added by r16-5305-gc38bf35f0c7fa1. This adjusts the assertion to not check OMP user-defined reductions (as they won't have import_export_decl called on them anyway). PR c++/119864 PR c++/122939 gcc/cp/ChangeLog: * module.cc (trees_out::write_function_def): Don't crash on OMP used-defined type reduction function definitions.
