This is wrong. __curunit (which is the assembler name) and $ba are different
and this is probably the reason for the effects you see.

I don't know why $ba is zero after start of a program (the cc65 runtime does
not clear it), but it is clear that it will have the value 8 later, since this
is the default value for _curunit. open() uses SETLFS to transfer _curunit
into $ba, so both are equal after opening a file.
