--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #1) > Preprocessed source? It is in the log file but you need to extract it. It starts with line: === BEGIN GCC DUMP === and ends with: === END GCC DUMP === You also need to remove "7966:" at the begining of the line. Looks to be template related too but I could be wrong.
