Robert posted a patch to fix it, at least I guess you are facing the same 
bug. Search in the mails.

I think the new malloc will break a lot of buggy programs because a lot of 
memory related bugs are hidded thanks to the 2^n feature of the old malloc.
I found various bugs in the editor when I ported the code to Linux because 
the glibc malloc reuses the memory very quick and you don't have "extra 
space" in most of the allocated buffers like with the 2^n malloc.
But I think the bug is the one pointed by Robert.

To DJ's incoming and send a mail to DJ. I think that's somewhere in the docs 
or the web, don't remmember.

I think the best is to put betas in public places and releases in the DJ 
server.
