I'm just curious: what about on OS X on a case-sensitive file system?
You can make a throwaway case-sensitive disk image to play with.

I could, if you could indicate how to do that.

Can you detail how to do such an image in order to test this?

Ah, sorry; should have done that in my first message to avoid the cycle!
Have a look at
 http://wiki.darcs.net/Development/Tips#dealing-with-different-filesystems

I have tried this and the error persists, so it's not a filesystem case sensitivity issue.

I then went to change the regexp to the alternate form (^|/)core(\. [0-9]+)?$ and the error went away. I guess in the end it proves to be a bug in the OS X regex implementation. Most likely it doesn't like empty alternative for the | operator, even though it is valid.
