in create_display_buffer_processor()
OCIO_ConstConfigRcPtr *config = OCIO_getCurrentConfig()
config seems to be garbled, following then leads to OCIO_abort()

@Sergey Sharybin (sergey): mind checking again?

Same thing here on Windows. This started yesterday at some point, another compiled version with hash 245065460f3 works just fine. If the user has set that color space in his startup file (like I did), Blender never starts and throws the 'Cannot find Colorspace' Error on startup.

I can confirm that the bug has been fixed, thanks, and keep up the good work.

also fixed on Windows, thanks!
