Description

Detected a segmentation fault in AppLayerParserGetTxCnt. One interesting fact, is the CPU usage on the flow manager thread, don't know if it could have impact or not. I can reproduce it consistently by replaying a packet dump (replaying at ~400Mbps).

Suricata has been compiled without optimizations.
