assertion failed / segfault in svn_ra_do_diff3
I recently caught a segfault / assertion fail in svn client.
svn, version 1.8.5 (r1542147)
compiled Dec 2 2013, 21:40:18 on x86_64-unknown-linux-gnu (built from sources on Ubuntu 12.04 LTS)
It was a reproducible segfault at command something like that
svn up -r XXXXXXX ..
Here is a backtrace, all coredumps are saved for future analysis.

After repo updating this crash disappeared. Before that crash I updated 'arcadia/yweb/robot/queuer' subtree to different revision (1403046) a couple of times and rolled it back to 1403047.

I just reproduced this issue on Subversion trunk and added a regression test
for it in r1604736.
The problem is most likely in the literal '..', which is accidentally passed
on as invalid file or directory name in this diff variant.
I'll see if I can fix this issue later today. (And then what it will take to
backport the fix to 1.8.x)

Oops, my bad! You're absolutely right, that was 'svn diff' command. And this mistake was the reason of crash 'disappearing': after that I built svn 1.8.9 from sources and got the same crash again, so it is reproducible.
Here is a backtrace for `svn diff -r 1403046 ..` invocation:

This stacktrace is for some invocation of 'svn diff'. There is no way you
can get this for an invocation of 'svn update'
(Update doesn't use any of the UI level diff logic)
So either you are using bad debug symbols, or you are mixing different
problems.

This is another reference to 'svn diff'
Git diff format is a UI level diff support flag, which was also abused for
the working copy walker in 1.8, but it is unrelated to svn update.
