Do you think that it is important enough to prompt an incremental 2.7
release? If not then it won't get out to users anyway.

Well, I don't know what standard distros of 2.7.x were made with 64-bit kernels. If none, then there's no problem. It then could only affect people who built from source, and we can tell
them how to fix it.

If there IS a 2.7.x distro iso file with a 64-bit kernel, then it should be fixed. This bug is completely "fatal" on 64-bit compiles, as the encoder rolls over from 0 to -16777216 counts, causing an immediate following error. And, this affects all 3 of the Pico Systems devices.
