[plt-dev] segfault with mzscheme trunk

The code is at http://web2.0collage.com/slseg.tar.bz2
When I run it on my x86_64 machine it segfaults, but doesn't on my
32bit x86 machine
If I get rid of the HMAC-SHA1 stuffer it works.
The error occures when I go to fetch anything in /app/
I asked on #scheme and jonrafkind suggested I should e-mail this list
Any suggestions?

I tried running it inside valgrind (to see if it was doing funny
things with the memory prior to the segfaul):
