I found the problem. It's a bug in gpasm. I attached a simple asm file
that exploits the bug.
The code is relocatable. gpasm generates the relocatable symbol for '$' as
('_$_' + line offset). There was a coincidence here that two code sections
referred to '$' at the same offset and created a duplicate label. To fix
this, we could add the code section name into the label or add in some kind
of global counter.
Any suggestions?
