[ERROR hir_ty::mir::borrowck] Terminator should be none only in construction

[Veykril]

I don't know how this was triggered as r-a worked fine after it restarted, but the logs were spammed with this until the thread this was running on stack overflowed and caused r-a to exit, thread 'Worker' has overflowed its stack.

I think the stack overflow is not related to the [ERROR hir_ty::mir::borrowck] Terminator should be none only in construction log.
