It turns out to be caused by Net::IP::Match::XS::match_ip

Is it a known issue that this module is not compatible with Apache::DB?

update

I was wrong,it still happens after I comment that line out, looks like a wild pointer problem in C,is there any wat to diagnose this issue?

update2

Looks like it's in-compatible with Apache2::RequestUtil->request
