svn assert failure: svn: /build/buildd/subversion-1.8.8/subversion/libsvn_client/merge.c:3105: merge_dir_deleted: Assertion `delb != ((void *)0)' failed.

[Danilo Piazzalunga]

Subversion crashed during svn merge from a parent branch to a child branch.

The commits to be merged from the parent branch include a replaced directory:

- svn mv orig_dir new_dir
- svn mkdir orig_dir

I will try to reproduce the problem with a minimal, self-contained test case.
