--- Comment #7 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Jason Merrill <[email protected]>: https://gcc.gnu.org/g:7b0a85ab6633f71e0488299b2b3a8e26b7cf7d78 commit r16-6396-g7b0a85ab6633f71e0488299b2b3a8e26b7cf7d78 Author: Egas Ribeiro <[email protected]> Date: Mon Dec 22 21:41:00 2025 +0000 c-family: Fix ICE with -MD and -fdeps-format sharing output [PR121864] When -MD, -fdeps-format=p1689r5 and -save-temps are used without explicit output files, they default to the same stream, which is invalid. The error message attempted to print fdeps_file, but this is NULL in this case, causing an ICE. Use out_fname as a fallback when fdeps_file is NULL to avoid the ICE and provide a meaningful error message. Fix suggested by Andrew Pinski.
