[leafnode-list] fetchnews segfaults

[Raymond Scholz <rscholz@xxxxxx>]

Hi!

Yesterday evening fetchnews aborted with a segmentation fault during
the fetch of a newsgroup.  This fault is reproducible, it occurs
during the fetch of a certain article from de.comp.security.misc from
my ISP's news server.

Tried with leafnode 2.0b8 and 2.0b8_ma2, my system is Linux / Debian
Potato.

I don't get a core file (ulimit -c gives me "unlimited"?!), but here
is a gdb session:

[...]
skipping articles 1-3789 inclusive (initial limit)
de.comp.security.misc: considering articles 3790-3989

Program received signal SIGSEGV, Segmentation fault.
0x400a6193 in strchr () from /lib/libc.so.6
(gdb) bt

and the strace output:
