It's a GCC bug, but there is a workaround for it in Stackless.  It 
sounds like the greenlet code you are compiling is using really old 
stackless code.  I fixed this bug in stackless CVS some time last March 
I think.

Make sure you're using the latest Xcode and whatnot too, of course.  
This is what I have:

% cc --version
cc (GCC) 3.3 20030304 (Apple Computer, Inc. build 1666)
