Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- The size limitation is given from the way columns, lines, blocks and location ranges are encoded in location_t, which is a 32-bit number. See libcpp/include/line-map.h comment above location_t typedef. If you have very long lines (I think more than 4095 columns), the code is badly formatted and -Wmisleading-indentation just doesn't make sense.
