Description

Segfault after updating to version 1.4.62

server crashed reproducable after a couple of seconds after an HTTPS url was accessed.
build withh pcre2

I guess there is a memory corruption before.

error.log:
2021-12-04 09:16:49: (connections.c.1467) connection closed - keep-alive timeout: 20
