--- Comment #3 from Marek Polacek <mpolacek at gcc dot gnu.org> --- (In reply to Marek Polacek from comment #2) > I think the compile-hog would also be visible with -Wduplicated-branches, > but that's not in yet (and it's unclear whether it will make its way in to > GCC 7). Nope: $ time -p ./cc1plus -quiet 78208.C -fsanitize=null -Wduplicated-branches real 0.04 user 0.04 sys 0.00 but it is a compile-time hog with -fsanitize=null -fdump-tree-original as Comment 1 says.
