Hello,

I'm writing on my next cc65 beginners tutorial issue for ABBUC Magazin.
It's about low-level programming with cc65. I started with an easy example, 
the ATARI Rainbow.

This is the program in pseudocode

while (nokey)
{
  wsync = colpf2 = rtclok + vcount
}

wsync is a byte at 0xD40A  (wait for horizontal sync)
colpf is a byte at 0xD018 ( color of playfield 2)
rtclok is a byte at 0x12 (part of internal clock, incremented every screen 
refresh)
vcount is a byte at 0xD40B ( current scanline )

This is my programm, to my knowledge, valid C code (but I'm not an expert)


----------------------

#include <atari.h>
#include <stdio.h>

typedef unsigned char byte;
typedef unsigned word;

int main(void)
{
    *(byte*) 0x2FC  = 0xFF; // clear keybuffer
    while (*(byte*) 0x2FC == 0xFF) // while no key pressed
    {
        *(byte*) 0xD40A = *(byte*) 0xD018 = (*(byte*) 0x12) + (*(byte*) \ 
	 0xD40B); // change bg-color every scanline
    }
    getchar();
    return(0);
}
----------------------

On compile with cc65 2.9.0 I get 

rainbow.c(46): Internal compiler error:
oursp != savsp (-2 != 0)
Line:  }
cl65: Subprocess `cc65' aborted by signal 6

Can anyone see what is wrong?
Or is this a compiler problem?

Best regards

Carsten
