I can't reproduce the ICE on Linux/x86. Could you post the

--------------
void BayerNearestNeighbor(unsigned char *outG, int sx, int sy)
{
int i,j;
for (i=1;i<sy-2;i+=2)//every two lines
for (j=0;j<sx-1;j+=2)
outG[(i*sx+j+1)*3]=outG[((i+1)*sx+j+1)*3];
}
-------------
It will produce such error message:
TestGcc32Bug.c: In function `BayerNearestNeighbor':
TestGcc32Bug.c:10: unrecognizable insn:
(insn 277 147 286 (set (reg:SI 122)

(nil))
