OK, I could condense the problem to a 75k zipped testcase (It is still the 11 lines
perl file that hangs). See here:
<http://www.openoffice.org/nonav/issues/showattachment.cgi/27695/perlfreeze.zip>

It is a standalone testcase, unfortunately it depends on the absolute path
it resides in. To reproduce unpack perlfreeze.zip to d: and then
do:
$ cd /cygdrive/d/perlfreeze
$ ./perltest.pl

and see it hang. (In rxvt/bash)

I could not condense the testcase any further, when I remove more
lines from openofficeorg_q4.ddf the error vanishes.

P.S: If you cannot unpack to d: choose a different location and change
openofficeorg_q4.ddf accordingly.
