--- Comment #17 from Janne Blomqvist <jb at gcc dot gnu.org> --- I have fixed resolve_ordinary_assign as part of a larger patch fixing similar issues in the frontend (you also need to change extract_int to extract_hwi). I can submit it once I have tackled the 32-bit regression Dominique reported on IRC.
