I spend time fighting SourceForge's Compile Farm (actually, I have few complaints about this aspect of their service; I think I'm getting more than I pay for) to build two different versions of SBCL for MacOS X, so that I can investigate the problems of RUN-PROGRAM on the PPC.
However, I can't reproduce the problem. At all. No matter how hard I try, all my RUN-PROGRAMs work fine.

So. How annoying. SourceForge's Compile Farm machines are clearly too good...
