The actor directives (.constructor, .destructor, .interruptor, and .condes)
can't handle a symbol that's already exported.
The relevant code does the checks in the wrong order.
For example, the following correct snippet does not assemble:
.export C
C: .constructor C, 5
The assembler outputs: test.s:2: Error: Address size mismatch for symbol 'C'
Exchanging both lines makes it work.
This fixes #1647; the patch is provided by 'kugelfuhr' and taken from there.
cc65 is a complete cross development package for 65(C)02 systems, including a powerful macro assembler, a C compiler, linker, librarian and several other tools.
cc65 has C and runtime library support for many of the old 6502 machines, including
- the following Commodore machines:
- VIC20
- C16/C116 and Plus/4
- C64
- C128
- CBM 510 (aka P500)
- the 600/700 family
- newer PET machines (not 2001).
- the Apple ][+ and successors.
- the Atari 8-bit machines.
- the Atari 2600 console.
- the Atari 5200 console.
- GEOS for the C64, C128 and Apple //e.
- the Bit Corporation Gamate console.
- the NEC PC-Engine (aka TurboGrafx-16) console.
- the Nintendo Entertainment System (NES) console.
- the Watara Supervision console.
- the VTech Creativision console.

The libraries are fairly portable, so creating a version for other 6502s shouldn't be too much work.
