Umm.  Kind-of.  You're not going to believe this, but it works fine when
I call it with --verbose.

I doubted my sanity, so I tried it without --verbose again.  Still  
gives the
"Abort trap" message.

Since this bug seems fairly esoteric -- a fairly contrived input  
example, not
always manifesting -- I vote that we not worry about it.  Maybe it's  
some weird
fink / OSX flaw in some underlying library that won't apply to the new  
fink
stuff for 2.5.x.  :)
