Missing Infill (on some parts) for Every N Layers

[cakeller98]

On some parts (verified no repair needed in netfabb) will have the infill fail when every N layers is 2
Same parts do not fail with infill every 3 layers, or 1 layer.

for example:
Layer Height: 0.24
Every N Layers: 1
success (Infill Generated)

Layer Height: 0.12
Every N Layers: 1
success (Infill Generated)

Layer Height: 0.08
Every N Layers: 3
success (Infill Generated - every 3 layers)

Layer Height: 0.12
Every N Layers: 2
FAILS

The part looks like a wagon wheel with four spokes, and a center hole (schematically)

EDIT >> (does not actually FAIL, but there is no infill included in the gcode output)

Perhaps it is the solid layers that are prematurely ending the infill?

if I set solid layers to ZERO, then:
Layer Height: 0.12
Every N Layers: 2
Perimeters: 3
Solid Layers: 0 <<== seems ot allow at least the infill to fill.

All testing done on commit: 0e1d893
Also all testing was done on a single STL files, which sometimes works, and sometimes doesn't depending on the settings, and it only seems to really have trouble when using the infill every 2 layers.

Could you please share your STL file and config.ini?

[cakeller98]

Here is a zip file containing the stl, the config, the output, and a log file from when I re-tested (note: used the above commit for testing)
BROKEN-Original(with stl, gcode, and log).zip

Here is a zip file containing the same as above, except it has been run through the netfabb cloud fix.
BROKEN_fixed-fixedbynetfab(with stl, gcode, and log).zip

and lastly, here is a screen capture of the the threads that "terminated" in tilinear.pm @ line 19:

UPDATE: re-tested with same config etc, but latest commit, and the problem is gone.
