crash just after loading Deflater.class

Hi there!

I've noticed that, with the latest snapshots of Kaffe, I've become
unable to run jar.  For a command line as simple as:

kaffe -verbosejit -verbosegc -verbose -c0vf test.jar .

I always get output like:

Loading java/util/zip/Deflater.class(/tmp/kaffe-inst/share/kaffe/Klasses.jar) [compressed]

/home/msc/oliva/src/kaffe/kaffe/kaffevm/mem/gc-mem.c:254: failed assertion `blk->free != 0'
Abort (core dumped)

This is not JIT-related, as the same problem occurs with an
interpreter-only engine.  It is not platform-dependent either, as I
can reproduce it on Solaris/sparc, IRIX 6.3 and RedHat Linux 5.0.  Can
anyone else reproduce it?  If that matters, I'm using zlib 1.1.3.
