**System Information**
Windows 10 Nvidia 940m
**Blender Version**
Broken: lastest master, compiled with default options
Worked: 2.79
**Short description of error**
It only occurs in windows. In linux it works perfectly.
When I export the UV layout blender crashes. Only with the PNG option. I have checked with 2.79 and it doesn't crash. Also if I compile with WITH_OPENCOLORIO = OFF it doesn't crash.
As it seems with the backtrace the crashes comes from OCIO.
RelWithDebInfos BF backtrace:
{F5052503}
BF console
{F5052512}
BF debug build assert::
{F5052518}
BF debug build backtrace
{F5052523}
Additionally, I also have random crashes when I add hemi lights (The crashes come when the light is updating in the preview window). If compile with OCIO off it doesn't crash either.
