Bug 282137: devel/apr1: proxy_fcgi:error after updating to 1.7.5

--- Description ---
Hello,

on FreeBSD 13.4 after updating apr1 to version 1.7.5, bareos-webui is not able
to authenticate user. Apache throws error "[proxy_fcgi:error] [pid 8084:tid
35662020608] (22)Invalid argument: [remote IP.AD.DR.ES:48532] AH01075: Error
dispatching request to : (sending stdin), referer:
https://example.com/auth/login

It seems there is also some weird behavior with nextcloud, unfortunately not
reproducible (I was unable to upload some files, but it had nothing with size
or type).

After downgrading to 1.7.3, everything started working.

Apache version is 2.4.62 with MPM_PREFORK disabled in favour of MPM_EVENT, but
reverting it makes no change.
