[leafnode-list] Bus errors on MacOS X with 2.0.0.alpha20030209a


today I was forced to rebuild my news spool (a disk problem, don't ask...)
and decided to try a new leafnode version. I've been previously running

However, when I tried the initial fetchnews, all I got was a bus error and
some crash dumps. Here's a gdb output of the crash. I'm running on Mac OS X

(13:31:58) backstreets:~/src$ uname -a

18:50:42 PST 2003; root:xnu/xnu-344.26.obj~1/RELEASE_PPC  Power Macintosh

and the news spool is on UFS partition. Newly compiled 2.0b8_ma10pre2 works.
