--- Comment #10 from Steven Bosscher <steven at gcc dot gnu.org> 2012-08-05 12:37:28 UTC --- (In reply to comment #7) > These memory requirements are solely due to the size of the .c file (1.8MB) . This is indeed excessive, we'll have to look into this. If you have preprocessed source and the compilation flags, can you please attach it? Or if you feel like helping out today, try to do a (non-bootstrap) build with --enable-gather-statistics, compile the file, and report back the resulting time and memory reports.
