Editor randomly crashes on macOS

[111116]

The editor will crash sometimes when I click on objects, names of primitives or drag the vertical split line. It's not 100% happening, but It will happen within a few clicks, usually upon draging the split line.

I've tried both on release version and debug version of v0.2.2.

Error message:

I'm gonna go ahead and say triggering a compiler trap that is 18 stack frames deep into Apple's code is probably not Tungsten's problem.

It may be an accidentially released object.
