After being away for several weeks, I find that in the current build (3133) after running a g-code file successfully, it cannot be reloaded. Nor can I load another g-code file. When I try a window pops up with the message:

Near line 1 of
</path/to/filename>
Cannot do g1 with zero feed rate.

Working back through recent builds, I found that the problem begins with 3116 [10-May-2017 23:28].

Version 2.8.0~pre1.3032 [10-May-2017 21:42] behaves as expected and I can load/reload another file in Axis without problem.

This is with linuxcnc-uspace running on jessie in a 4.4.66-rt79 kernel.

A couple similar problems created at that version "3116" you
mentioned were reported and fixed
https://github.com/LinuxCNC/linuxcnc/issues/269
https://github.com/LinuxCNC/linuxcnc/issues/271
I'm sad, but it sounds like there's yet another problem lurking
there.

However, I didn't reproduce your problem here. Based on what you
described, here are the steps I followed:
* start the sample configuration configs/sim/axis/axis.ini
* click the "reload" icon in the toolbar to reload the splash part
program
I tested with v2.8.0-pre1-3128-gafe82611f, which is after version
3116 that you said you identified as leading to the problem; and at
v2.8.0-pre1-3133-g6a3b4a226 which you also mentioned.

Can you let me know the specific steps you follow to reproduce the
problem? Please reproduce it with configs/sim/axis/axis.ini if you
can, or let us know if it requires a specific configuration. It
could potentially also depend on the loaded part program.

I saw something similar in master (2.8.0~pre1-3133-g6a3b4a2263) on
Wheezy/rtai yesterday. I'll try to reproduce it tonight.
