A mentor on the team I worked with in Massachusetts was at a district competition today, and noted that a number of teams seem to have freezing/stuttering problems on the field. While he didn't verify that the teams were having other problems (which very may well could be the case), it sounds similar to the problems I was experiencing before the patch.
Due to FIRST not releasing at least an optional official fix for this, I've decided to post an unofficial fixed binary to the
original bug report (direct
download link), for those who may not know how to fix the problem themselves. For anyone looking at the Driver Station versions, it will show up in diagnostics in 'Lib:' as 'C++ 2014 NT Fix'
Unfortunately, I haven't been able to verify it on a cRio as I don't have access to one at the moment -- if any of you can do this, that would be great. However, the original WPILib binary is 13.0 MB, and this one is 13.1 MB, so I expect that it should work, as it worked for RobotPy's version of WPILib when we used it.
