Re: Illegal instruction when running plmerge or a built app

[Alister Hood]

OK, thanks, that seems more promising - no illegal instruction running 
plmerge when building things.
But it still crashes when I try to run any app.  After also rebuilding 
gnustep-gui with debugging enabled, here's what I get:

Program received signal SIGILL, Illegal instruction.
