Yes, it's a Mac problem.  Something that changed in OSX 10.5.

Very possible.  But it's only forks that make it into OSX  
CoreFoundation.  I see a lot of forks in the GRASS source and this is  
the only one (so far) that has caused the CoreFoundation problem, but  
maybe they're just waiting to cause trouble.  In this case, Freetype  
gets into corefoundation.  I just tried a X monitor, same error.

... ah, we have a bug report already: http://trac.osgeo.org/grass/ticket/377

Michael mentions labels and the forking problem, though the report is  
for a more specific problem.
