That's my way of giving multiple error messages - I don't exit on the 
first one.  Since DMD expects that the error function exits the program, 
it often does things like sets objects to NULL that it later calls.

I need to go through the code some time, identify all the errors, and 
make sure it doesn't destroy itself.  It's on the TODO.

k.  I'll make a mental note not to report any more "second errors" as 
bugs.  Hope I don't lose it.

Huh?  What were we talking about again? :p
