svn segfault
Hi!
I'm trying to lock file with the latest svn from trunk and after:
svn lock 0001.asc
I got segfault. Here is the gdb session:

Hi!
I checked my subversion/lib directory and as you suspected I have one
old library: libsvn_ra_dav library. I removed binaries from
subversion/lib then I rebuild whole subversion tree.
Now svn lock works fine.
My repos was fsfs backend and working copy comes via webdav (http
layer). This segfault was independent of the contents of the file.

It looks like apr got a null comment which should have been fixed by
r14057 last month, are you using old libraries?

Can you tell us everything? Where did the working copy come from?
What are the contents of the file? What other properties are on it?
What kind of repository, FSFS or BDB?
We need a reproduction recipe to debug this.
I can't reproduce with r14672 of trunk, in an FSFS repository over
http://, by the way. The file is empty, and there's nothing else in
the repository. I just did the simplest thing: created the file
"0001.asc" and locked it:
$ svn lock 0001.asc
Authentication realm: <http://localhost:80> Subversion repository
Password for 'kfogel': ********
'0001.asc' locked by user 'kfogel'.
