Description
I'm running a 2-URL merge, and svn is aborting when trying to resolve conflicts on a directory that's been added both locally and as part of the other branch being merged in. I cannot reproduce this using simple setups, I have not been able to isolate what exactly triggers this behaviour, but it is reproducable on my repository.
Here's the exact command that I run:
svn merge ^/trunk ^/branches/feature/sempv2_vpn_mon_7 .
It produces many pages of add/modifies/deletes (the merge involve thousands of files), and then it starts interactive resolution of the conflicts.
Summary of conflicts:
Text conflicts: 40
Tree conflicts: 64
I start by choosing "mf" for the first 5 conflicts, and then when it get to the 6th conflict, it prints this:
Merge conflicts in 'solcbr/common/commands/config/about/aboutCommands.py' marked as resolved.
Searching tree conflict details for 'solcbr/common/commands/config/about/user' in repository:
svn: E235000: In file 'subversion/libsvn_client/conflicts.c' line 2257: assertion failed (start_rev > end_rev)
Aborted (core dumped)
For this path the "user" diroctory was added in both the "mon_7" branch and in the local branch.

I have a 39M core file. Should I attach a compressed version of it?
