I just modified the Swig generated svn_delta.c so that
_wrap_svn_txdelta_apply thinks
it is called with parameter pool = undef, forcing it to use a global pool
in the construction of
the magical md5sum. svn-git crashes with this, so its pool handling is not
to blame.

So back to your proposal, with the following patch svn-git has benn running
without crash for 15 minutes now.

It has the consequence that it breaks programs that care for the magical
md5sum, though.
But svn-git isn't affected (the way it calls SVN::TxDelta::apply makes sure
that the
magical md5sum is discarded).

Cheers, Roderich
