Ok, but simply calling a subroutine shouldn't cause a buffer overrun 
should it?  Especially when none of the arguments being passed to the 
subroutine are dynamically allocated.  I'm beginning to suspect it's a 
problem with the compiler actually.  Maybe the stack that holds 
subroutine arguments isn't big enough.  And when my problematic 
subroutine call is 4 levels deep or so like it is, then there isn't 
enough room on the stack for it's arguments.
