Problem summary
Nuke crashes after rendering an odd number of .exrs in terminal mode when the script queries the file metadata in an OCIO context knob and contains an OFX node, like the old OFlow node or a F_ReGrain node.

On Linux, after rendering the terminal returns a segfault/crashes

On Mac, after rendering Nuke crashes and OSX shows a warning

On Windows, there is a long pause before the Command Prompt returns to user control
