Confirmed with:
$ wget http://www.phoronix-test-suite.com/benchmark-files/c-ray-1.1.tar.gz
$ tar -xzf c-ray-1.1.tar.gz
$ cd c-ray-1.1
$ make clean; make CC="~/bld/trunk/install/bin/gcc"
rm -f c-ray-mt.o c-ray-mt

$ ./c-ray-mt -t 32 -s 800x600 -r 8 -i sphfract -o output.ppm
c-ray-mt v1.1

I'll bisect this.
