I'm running latest version from Git, and when slicing model I get this:

$ git rev-parse HEAD

Model is this one: http://www.thingiverse.com/download:718624

Running Ubuntu 14.04, x86.

Exporting GCode from GUI seems to work ok.

I can't reproduce this on OS X. I will try on Ubuntu.

@alexrj alexrj added this to the 1.2.1 milestone Oct 17, 2014

I believe that issue 2308 is the same as this one. I got the error using the GUI(1.2.0) on Mac OSX 10.10.

Okay, I can reproduce this on Ubuntu x68 with current HEAD.

alexrj commented Nov 8, 2014

I fixed this. It was caused by the Clipper library changing some point coordinates in x86. I applied a workaround.

Just a note:
I encountered this in 1.2.5 Experimental, but not in 1.2.6 Experimental.
G-code data ends in middle of "sentence" and a partial model is printed on some complex models.
(I cannot share the file that fails unfortunately, trying to reproduce with a open file.)
Platform was 32 bit x86 which seems to fit the original issue.
