It might be helpful to look at the disassembly of the offending .cls
file (jad is your friend).

I don't think so. The compiler works on one function at a time.

It seems more likely that something is wrong with the way the compiler
is assigning local variable numbers within a function.

But that doesn't explain why the problem goes away when you split up
the file, or why there is a problem with ERRLFUN, which doesn't seem
particularly exotic.
