Description

I have a pcap which crashes Suricata (3.2.1 and latest in master). Log files are produced but the process dies - this happens both when running suricata with the -r flag and the pcap and when running in unix socket mode.

I can provide the pcap upon request.

Output from the console:

suricata: detect-engine-hsbd.c:190: DetectEngineHSBDGetBufferForTX: Assertion `!(htud->response_body.content_len_so_far < htud->response_body.body_inspected)' failed.
zsh: abort (core dumped)  suricata -c suricata.yaml -l /tmp/ -r

This happens when the libhtp settings contain:

           # Can be specified in kb, mb, gb.  Just a number indicates
           # it's in bytes.
