Debugging old versions would be a waste of time because I am not  
supporting them. Benjamin should upgrade. Leafnode versions before 1.11.3  
have security relevant bugs and should not be used anyways. macports.org  
has 1.11.8 for instance.

When debugging 1.11.8 and the latest slrn versions, on systems where  
strace isn't available, truss or ktrace might be, and might be used to  
figure if for instance the nntpd crashes when entering particular groups.  
In such a case, I need a stack backtrace (see the FAQ) to debug that  
further, or a test case, or a plausible patch.

HTH.
