--- Comment #1 from Manuel López-Ibáñez <lopezibanez at gmail dot com> --- This is probably a warning from the middle end with a printf %-code not supported by the Fortran FE's pretty printer. The solution is to either add support for it in the FE or switch to the middle end pp when entering the middle end. There are several bugs like this one. Another solution is to either not call into the middle end at arbitrary points during parsing only during gimplification (not sure if this is the case here) or move the warning to the FE (middle end warnings should be avoided if possible).
