Subject: traps: apache2: general protection fault in libapr-1.so.0.7.0

Package: apache2
Version: 2.4.48-3.1+deb11u1
Severity: normal

Dear Maintainer,

Just noticed apache2 crash in dmesg.

[62643.929073] traps: apache2[821205] general protection fault ip:7f80b42c9556
sp:7ffeb6193880 error:0 in libapr-1.so.0.7.0[7f80b42b3000+22000]

I have freshly installed apache2, nothing is running on it, literally just a
"webpage under maintenance" index. But with TLS configured via letsencrypt.
Also system is freshly upgraded from buster, however, entire apache2 has been
nuked and reinstalled from the scratch, so it should be very clean, apart from
TLS config which I put back as it was before upgrade.

This is my 000-default.conf file (minus comments which I deleted)
