Hi

I've been hit with a problem whereby a certain combination of log messages and ignore/trigger settings cause logfetch to dump core during a memmove() operation. Same on both versions 4.3.4 and 4.3.3. It only seems to happen when I have an "ignore" clause (doesn't need to match anything) and a trigger clause that matches a line in the logfile.

Backtrace from gdb:

#0 0x00002acb0153cdaa in _wordcopy_fwd_dest_aligned () from /lib64/libc.so.6 #1 0x00002acb0153b1d0 in memmove () from /lib64/libc.so.6 #2 0x0000000000404030 in logdata (filename=0x5192d0 "./named.log", logdef=0x519268) at logfetch.c:315 #3 0x00000000004042cb in main (argc=<value optimized out>, argv=<value optimized out>) at logfetch.c:963

I've isolated the "logfetch.*" files from /tmp, and the 8 lines of log that trigger the problem for me, so it's easy to reproduce the fault with these files. In some cases I can avoid the problem by reducing the logfile down to less than the "maxbytes" setting in client-local.cfg, or increasing the "maxbytes" value to larger than the logfile size.

Short of learning more C, I don't know what more I can do to find/fix the problem.
