Build error: error in backend: Invalid operand found in inline asm: '#OC_ROW_IDCT

[Henrik Skupin]

Hi all,

I'm trying to find the changeset which has been caused bug 711794
(Firefox 9.0 Crash [@ js::Shape::finalize ]). For that reason I have to
compile builds between Aug 28th and Aug 16th this year. Sadly I always
end-up with the following compiler error. Does anyone know what's wrong
here?

Looks like bug 697821. Check out the related bugs, too…

I think I "fixed" it by adding:
CC=clang
CXX=clang++
to my .mozconfig, but that might have just happened at a similar time…

Later,
Blake.

Thanks Blake! At first that didn't help. Now I have applied the attached
patch from that bug and it seems to work for build from Aug this year now.
