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.
