I'm having the same problem with ICMP in 1.8.3:


A snippet:

Here is some mail I sent to Marty this morning which has some other
ideas on this problem...

Hi Marty,
        I have just been corresponding with Brennan Bakke
<bbakke () solcon nl>
who reported finding bits of snort rules in logged ICMP packets (on the 
security focus incidents list).  I told him about the build 89 fixes and
suggested that these might fix his problems.  Someone else pointed out
(quite rightly) that the ICMP packets should not go anywhere near the 
stream4 preprocessor!
