memory leak

[fyy-100]

function: htp_mpart_part_handle_data
line: part->parser->pending_header_line = bstr_add_mem(part->parser->pending_header_line, data, len);

if memory not enough, bstr_add_mem return NULL but not free part->parser->pending_header_line old memory

Thanks for this report, would you like to submit a fix ?
Suricata does not use this part of libhtp (multipart parsing)
What do you use libhtp for ?

I try to use libhtp to instead of nginx with modsecurity ：）
