Subject: Fix a potential un-intialized variable usage warning.
X-Git-Tag: 2.5.0-alpha2-ci-test-only~2587
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4be1913dd2ad7ac09c8ba948e355c062e44ee2aa;p=thirdparty%2Fapache%2Fhttpd.git

This can not be a runtime ixsue, because, in such a case, we would assert and abort before.

 PR 59819.
