Have you tried the latest Buildbot builds?
I had a similar bug that was fixed some time ago: https://developer.blender.org/T52479

I tried v2.79.1 77dccbf just now - same thing, it doesn't track one frame in any direction.

I can not reproduce the bug on Linux.

Try running blender with --factory-startup command line argument and try reproducing the bug again. If the bug still happens, attach .blend file and small image sequence or a small video used for tracking which demonstrates the issue.

I accidentally found that there is one very important factor that I missed: sequence should start from any frame except 1st.
There is archive with simple sequence and two blend files: one starting from 1st frame, other from 28th frame. The latter one demonstrates this bug.
