Compatibility with opencascade-6.8

[GoogleCodeExporter]

I'm running on Arch Linux and recently updated to opencascade-6.8.0 from 6.7.1. 
I'm getting "Segmentation fault (core dumped)" when starting heekscad. When I 
downgrade to opencascade-6.7.1, heekscad started without any issue.

Below is the gdb backtrace:
Starting program: /usr/local/bin/heekscad 
[Thread debugging using libthread_db enabled]

Program received signal SIGSEGV, Segmentation fault.

Do you use HeeksCNC plugin with HeeksCAD ?

Yes, I mainly use HeeksCNC, should I be reporting the issue somewhere else?

If I update to opencascade-6.8.0, compiling latest heekscad will result in the 
following error
