34 <PRE>That's understandable, my network has suffered through several DDoS's.
35
36 Anyway it's GCC 3.3.4.
37
38 I'm currently using a test server to try and recreate the crash as I can't
39 risk them crashing on my main network again. If I can get it to happen
40 again I'll post the debug log.

54 &gt;<i> I appologise for the rudeness of my reply last night, there was no need
55 </I>for it, my IRC network was DDoSed last night, and 3 of our servers went
56 down.. but you dont need my life story.
57 &gt;<i>
58 </I>&gt;<i> You are right, there is a - in all exception lists, it just seemed odd
59 </I>that i used /os exception list.
60 &gt;<i>
61 </I>&gt;<i> If you can re-create the bug, would it be possible to see if /os exception
62 </I>list returns the same corrupted results?
63 &gt;<i>
64 </I>&gt;<i> Also, what version of GCC are you running? It may be a compiler issue.

84 </I>&gt;<i> &gt;Wow that was an extremely rude reply.
85 </I>&gt;<i> &gt;
86 </I>&gt;<i> &gt;First off other then neglecting to include the O/S info I gave all the
87 </I>&gt;<i> &gt;information the manual asked. Which it's running Slackware 10 with kernel
88 </I>&gt;<i> &gt;2.6.7 on an AthlonXP 2500+ with 256MB of RAM.
89 </I>&gt;<i> &gt;
90 </I>&gt;<i> &gt;Second off it's a stock version of services. The character '-' is always
91 </I>&gt;<i> &gt;placed before the exception reason when you issue the view command
92 </I>(versus
93 &gt;<i> &gt;the list command). I'd highly recommend you give the '/operserv
94 </I>exception
95 &gt;<i> &gt;view' command a try.
96 </I>&gt;<i> &gt;
97 </I>&gt;<i> &gt;Finally there was no back trace. I'm currently trying recreate the crash,
98 </I>&gt;<i> &gt;but it may very well have been due several other factors to, include the
99 </I>&gt;<i> &gt;length of time services had been up and running as it appears to me that
100 </I>&gt;<i> &gt;something was handled incorrectly with the buffer, which could of been a
101 </I>&gt;<i> &gt;progressive problem. One other piece of information that is worth adding
102 </I>is
103 &gt;<i> &gt;it only happened with the issue of the 'exception del num' command, but
104 </I>&gt;<i> &gt;appeared to be fine with the 'exception del host' command... as soon as I
105 </I>&gt;<i> &gt;can recreate the crash I'll gladly provide the debug log.

119 </I>&gt;<i> &gt;&gt; Firstly, please don't send HTML emails to this list. Thanks.
120 </I>&gt;<i> &gt;&gt;
121 </I>&gt;<i> &gt;&gt; Anyway, this seems to be odd behaviour indeed, looks like a buffer
122 </I>overrun
123 &gt;<i> &gt;somewhere.
124 </I>&gt;<i> &gt;&gt; My official responce would be: &quot;RTFM FAQ Z.3&quot; Which describes fully
125 </I>how
126 &gt;<i> &gt;to report bugs.
127 </I>&gt;<i> &gt;&gt;
128 </I>&gt;<i> &gt;&gt; On the other hand, has this version of services been modified in any
129 </I>way?
130 &gt;<i> &gt;the appearance of the - charactor in every exception makes it appear so,
131 </I>if
132 &gt;<i> &gt;it has been modified, dont expect help :)
