Can you give us an idea of what was last changed before this started crashing? Is this the first compile, or have you had it working before?
On first glance, I’m going with the theory it’s due to case sensitivity (from what I just Google’d, my theory appears to be correct), which appears to be a non-default setting on Mac.
Supposedly this bug was fixed last year, but I see you’re using 4.14 anyway. I know some of these questions didn’t get answered, but hopefully they can help give some insight.
Let me know if this has helped.
