Well I can write a few hundred lines in Intel syntax and understand AT&T syntax, but the problem is not with the assembler code itself, it's valid. Seems that gcc runs out of registers or something. It may be of help if we replace some of the hardcoded register names in asm with generic ones, such as r0, r1... if gcc asm supports such a feature. I'm using the gcc-3.2.3 included in rock-linux-2.x.y (it's the standard gcc + the IBM stack protector security patch) and have no problems at all. Everything compiles and works.

I used gcc-3.2.2 included in Mandrake 9.1 and see the error, but I don't see it in DJGPP with gcc-3.2, so...
I will probably release GRX 2.4.6 and make a note in the "know problems" page to recomend to use -O1 if the error appears.

Which reminds me that I'm using gcc-3.2 from MinGW, and don't see the error either.

The error is probably in one of the -O2 specific register optimizations. You're getting the error, so you can disable the delta(-O2, -O1) optimizations one-by-one, see exactly which one generates the error and recommend turning it off.
