--- Comment #8 from Manuel López-Ibáñez <manu at gcc dot gnu.org> --- (In reply to Andreas Schwab from comment #6) > May be a dup of bug 57201. I think not: that one is about warnings appearing after preprocessing (and we know why this happens). This one is about warnings disappearing (and we do not know yet why this happens).
