--- Comment #1 from Bernd Schmidt <bernds at gcc dot gnu.org> --- People will be more likely to look at it if there's a preprocessed .i file that reproduces the issue, ideally with a cross compiler rather than a native bootstrap. If it only occurs when bootstrapping, narrowing down the offending commit would be helpful.
