Actually, I do have one more thing for you to try. You said you're using
a perl script that basically does the following:
> my $client = new SVN::Client( auth =>

Can you change that last part to be:
  my $subpool = SVN::Pool->new_default;
  for my $i ( 1 .. $n ) {
     $client->merge (..., $subpool);

Some of these client functions aren't as well behaved as they probably
should be. They make allocations of out the pool passed to them, but we
don't clear the pool. We should probably be using a subpool for
temporary allocations in the svn_client functions, and only using pool
parameter for data that needs to last longer.

BTW, is there some way you can narrow down what caused the segfault with
the property merge? I'd like to make that problem go away too.
