Try deleting options.txt from the .minecraft folder (it appears that something is making the game allocate an insane amount of memory while reading a file, otherwise the only other solution that I've seen for this issue is to reinstall the game from scratch; however, since the launcher verifies that all the game files match the ones on Mojang's servers on every launch the issue is likely in a data file (game settings, resource packs, and saves).
