Re: svn 1.8.1: segmentation fault on merge

I encountered the same problem with subversion-1.8.3
(CentOS5, httpd-2.4.6):
svn merge ends with sengmentation fault.

I re-compiled svn with the --enable-maintainer-mode configure option.

Here is what I get:
% libtool --mode=execute gdb --args /opt/local/bin/bin/svn merge
--non-interactive --dry-run http://reposrv/p1/branches/branch1/work .
/usr/bin/libtool: line 6823: LC_ALL: command not found

/usr/bin/libtool: line 6823: LC_COLLATE: command not found
/usr/bin/libtool: line 6823: LC_MESSAGES: command not found

Now, when I run:

svn mergeinfo --show-revs eligible http://reposrv/p1/branches/branch1/work .

I get:


And now using the --revision option to merge:

svn merge --revision XXXX:YYYY --non-interactive --dry-run
http://reposrv/p1/branches/branch1/work .

it works. So without --revision it segfaults, using --revision it works.
I should mention that there already exists a mergeinfo containing a
number of already merged revisions which do not appear in the mergeinfo
list (as expected).
