Exclamation Bug!!!

"More questions" has been covered pretty well already by others.

For gpuowl -use option timing and tuning, I use the Windows batch file attached.
Pass zero and one run together; other passes individually. Edit the gotos and sets from one pass to the next, to change the control flow and -use options in effect, respectively.
That is what I did to produce my previous posts of tuning results. See the comments at both ends of the file, for more info. (Had to zip it, the forum won't accept a .bat file.)

Please post your tuning results.
Thanks!

But first, just want to say that there is a bug on the program.

I'm using gpuowl v6.11-134-g1e0ce1d.
