Thanks for putting up binaries to test, that should help people figure 
out what's up.

I get this same output when I use Mono from SVN trunk.  I get the bad 
output with Mono 2.0.1 (the only other version I had available to test).

Normally I'd say you should file a bug, but as this seems to be fixed in 
trunk, perhaps that isn't necessary.  I'd recommend following this 
procedure to build Mono in a parallel environment so you can test for 


Actually, looking again at your output, I see you are probably building 
Mono 2.4 yourself.  There have been updates since March 11th, so maybe 
if you updated your mono-2-4 branch checkout the bug would be fixed?
