I'm using the one that's with cw 9.2. I can't make a reproduction - it's located in awful big 5 segments shared library and the function itself is more than 400 lines of code :(

and this line is making it:

if I change it to this: for(i=(dir>0)?0:(linesize);(dir>0)?i<(linesize):i>=2;i+=dir)
the error is gone :)
Maybe should split this loop in 2, this way looks nasty and is maiking strange errors :)
Which version of the CW ARM compiler are you using? I'm fairly sure this is an error that is fixed in 9.3, but I can't be sure without a bug report and reproduction case.
BTW, there's not much advantage in using optimization level 3 and 4 for PNOs. Going to opt 2 will get you most of the benefits, while avoiding some optimizations that can really increase code size.
