Hi all,

I have an odd issue that I wonder if anyone's seen before (before I dig into the guts of SVN::* myself...)

If I let SVN::Client automatically handle the connection pool itself, I get a segfault:

use strict;
use warnings;

use SVN::Client;

my $ctx = new SVN::Client;
$ctx->cat(\*STDOUT, "https://some/svn/url", "HEAD");

The backtrace of the core is: 
(gdb) backtrace
#0  0xfe330f20 in ?? ()
#1  0xfeec41dc in ?? ()

So it occurs in the destruction of some xs code - presumably the SVN connection. On a hunch, I tried creating and freeing the pool manually:

use strict;
use warnings;

use SVN::Core;
use SVN::Client;

my $pool = SVN::Pool->new_default;
my $ctx = new SVN::Client;
$ctx->cat(\*STDOUT, "https://some/svn/url", "HEAD", $pool);
undef $pool;

Which works a treat. Anyone have any familiarity with the SVN::* internals before I go hunting?

Update: I loaded in all the symbol files I could think were relevant and discovered in the backtrace is xml related (and I'm linked against libxml2).
