On windows, try the latest revision of dolphin, and see if that fixes it.
With Arch, make sure you have all of your libraries up-to-date. There are some that Dolphin uses that you'd need up-do-date, though, I can't say which, since they already seem to be a part of my updating repertoire when first installing the operating systems. A crash like that seems, to me, to signify a missing library. To try to figure out which ones cause the crash, run Dolphin from the terminal or terminal emulator (I don't know which one Arch has; I'm a Ubuntu guy, myself).
