While working on tracking down an oddity, I discovered a way to force a core.

I built snort with --enable-debug.  I added the following lines to snort.conf:

 config reference_net:
 config daemon

Each time I start it, with that setup, I get a core.  Here's the backtrace:

#0  0xff1b6f3c in strlen () from /usr/lib/libc.so.1
(gdb) bt
#0  0xff1b6f3c in strlen () from /usr/lib/libc.so.1
#1  0xff201c20 in _doprnt () from /usr/lib/libc.so.1
#2  0xff203ba0 in vprintf () from /usr/lib/libc.so.1
#3  0x19b38 in DebugMessageFunc (level=2, fmt=0x63f38 "Args: %s\n")

#5  0x22164 in ParseRule (rule_file=0xb5808, prule=0xffbef688 "config daemon",
    inclevel=0) at parser.c:551
#6  0x219cc in ParseRulesFile (file=0xa2400 "", inclevel=0) at parser.c:250
#7  0x2bb34 in ReadConfFile () at snort.c:2283
#8  0x28f00 in SnortMain (argc=1, argv=0xffbefcf4) at snort.c:245
#9  0x28cd4 in main (argc=1, argv=0xffbefcf4) at snort.c:95

Odd thing is, using the same config file and a non-debug version of snort--It
doesn't core.

Any ideas?
