cr1.8 and tilesortspu on Windows OS

Hi.

Maybe you are having the same problem that we have been experiencing.  I, also, have had problems using Chromium v1.8 with the tilesort spu.  I did eventually get it to work by removing compiler optimization setting in the "options.mk" file found in the chromium directory.  Change the optimization setting from 1 (compile with optimizations and no debug info) to 0.  I don't know if this is the same problem as you are experiencing, but it is worth a try.

After you change your "options.mk" file setting to 0, do a 'make clean' and a 'make'. 

See if that helps.
