a simple svn merge requires 9GB of VM.

Hi,

I have a test case using partially checked out working copies.
The "svn merge" operation in this test case requires 9GB of VM
and takes a long time.
On machines that do not have that much memory, it fails either
with "Out of memory - terminating application." (Windows) or
with "Could not resolve hostname `svn': Temporary failure in name resolution (http://svn)".

FWIW, here is the complete test case that I can use to
reproduce the error (tested under subversion 1.5.2 and 1.5.4):

  svn co -N http://svn/surf/trunk surf_trunk
  cd surf_trunk
  svn update -N src src/surf src/surf/SurfDB src/surf/SurfDB/SurfDB src/surf/SurfDiagnosis src/surf/SurfDiagnosis/SurfDiagnosis src/surf/gui src/surf/SurfRequestBroker
  svn merge --force --depth=infinity -r15395:15397 http://svn/surf/mods/ga-test@15397 .

If I check out a complete working copy, i.e.
  svn co -q http://svn/surf/trunk surf_trunk
  cd surf_trunk
  svn merge --force --depth=infinity -r15395:15397 http://svn/surf/mods/ga-test@15397 .

it takes very little memory and much less time.

I guess this may be related to the problem reported by Peter Kahn
on 10/17/08 ("svn merge fails "Out of memory - terminating application." or
Tortoise runtime error).

I'd say it's a bug.

Is anyone working on this already?
Should I file a bug report?

Cheers,
Carsten.
