Hehe
the poll address is fake just intentionally, ok so I downloaded 4.10 ver for my windows machine and it acts the same when i'm trying to mine with my gpu, bfgminer-3.10.7-win64 works fine with the pool i use , bfgminer-4.10.0-win64 does not. The same issue is on linux. May it be a pool is incompatible? I am mining there with dmaxl's cgminer but it's not updated anymore.
Please use
http://luke.dashjr.org/tmp/code/webisect/webisect.php to identify the regression.
1. Enter anything random for Session name, click Go.
2. For "Working commit:", put bfgminer-3.10.7
3. For "Broken commit:", put bfgminer-4.10.0
4. Click "Start"
5. Wait for the webserver to build a CUSTOM version of BFGMiner (ignore the version it claims to be when you run it).
6. Download the custom build, and test if it works. Click the relevant button.
7. Go back to step 5 until it gives you a "verdict" on which change is guilty for breaking it.
8. Post the final result here.
