On macOS 10.14, futimens in lib/futimens.c calls fdutimens in lib/utimens.c which calls futimens again, recursing until the stack is full. This cause Fcopy_file to crash, for instance.

No doubt I've made a silly configuration error, but I've wiped the (out-of-tree) build directory, regenerated configure and all. As expedience I commented out the futimens definition. Not sure how this is supposed to work really -- what am I missing? HAVE_FUTIMENS is set in config.h.

This feels like Bug#39948. I suggest cloning the source directory from 
git master, and starting afresh. Merely wiping out the build directory 
does not always suffice (I don't know why).

Thanks, and you were right. After carefully removing all non-versioned files from the source directory, the problems went away.
Closed.
