Then lets see if you can explain this because i can not:
 - Then problem is inside SplashOutputDev.cc because you can compile 
everything with -O2 and it fails, but if you touch SplashOutputDev.cc and 
make it compile with the -fno-regmove it works.
 - Adding the following patch makes it work

                         (SplashCoord)x3, (SplashCoord)y3);

and i can't see how much that can change things.

My compiler is gcc version 3.4.3 (Mandrakelinux 10.2 3.4.3-7mdk)

Obviously all help is welcome.
