Summary 06724: gauntleg, gauntdl: Various Effects Cause More Damage than they probably should (64-bit Only)
Description Several effects cause more damage than they should, probably because they are hitting more times than they are supposed to. Can kill enemies and players with high health when they are not supposed to. Effects affected include green and red barrels (any explosion in general), magic, turbo attacks, certain boss attacks.

Mame 32 Video:
Steps To Reproduce Just use said affects. Walk up to a Golem(Giant Rock Creature) or Polar Bear for Ice Domain and use level 2 turbo or magic and watch it die instantly. Step on a red barrel and watch 2000+ health character die when it should only cause significantly less damage.
Additional Information This is likely already a well known issue, but I was prompted to make a bug report on this because I couldn't find a bug report on this. Also I've been hearing talk of discontinuing 32-bit versions of mame. This, or these(since it affects alot of things) glitches do not happen in the 32-bit builds of mame.

I have confirmed that this only happens with DRC enabled. Running with nodrc fixes the bug.
