I'm getting an "argument index out of range" error with v1.4 on a 290. Works fine on 1.3.2. Tried changing intensity values, taking out "experimental-kernel" but no luck. Anyone else?
This is a problem with nicehash and v1.4. Use a different pool or run 1.3.2 on nicehash.
Will try to provide a fix.
The root of the problem is that nicehash sometimes uses extremely long extranonces . This violates some of the optimizations I made for v1.4.0 which causes this error (it should have printed a nice log message but there was a bug there which ended up in this cryptic message).
