The line in $evalstr that causes the stack fault is:
if ($self->{conf}->{scores}->{q{WLS_URI_OPT_377}}) {
Which is on line 21720 (out of ~30800 lines). From what I've gathered, each
rule in the .cf files results in 4 lines being strung together in $evalstr:
if ($self->{conf}->{scores}->{q{<RULE_NAME>}}) {
<RULE_NAME>_uri_test($self, @_); # call procedurally for speed
}
It doesn't matter which rule is on line 21720 (as I've changed them around
to make sure it wasn't specifically WLS_URI_OPT_377, from
sa-blacklist.current.uri.cf), It seems when you get to line 21720 w/ a 64MB
stack on FreeBSD 5.4 w/ perl 5.8.7 etc, etc. that you've ran out of stack
space. This is part of the gdb bt from a perl5.8.7.core that I had:
