Subversion segmentation fault for 1 repository

[Jakub Nadolny <jakub.nadolny@carrywater.pl>]

Hi,

I've changed hardware in my server from i386 to AMD64 and everything works fine
except one SVN repository. 

When I try to access it, there is following error:
  svn: OPTIONS z 'http://some.local.ip.address/svn/repo-name': Could not read status line: connection was closed by server (http://some.local.ip.address)

in Apache error log:
  [notice] child pid 3504 exit signal Segmentation fault (11)

I've thought it might me dav_svn issue but:
  svnadmin verify repo-name
gives following result:
  Segmentation fault

The same is with:
  svnadmin recover repo-name

  Repository lock acquired.
  Please wait; recovering the repository may take some time...
  Segmentation fault

This repo is very big - server repo directory is 7.1 GB. Maybe this is a reason
for that? All other repositories work fine, although they are much smaller. 
 
On i386 machine this repository, just copied from amd64 works fine.

Any help will be appreciated.

Regards,
Jakub
