The fix in trunk (2.5) is
http://svn.apache.org/viewvc?view=revision&revision=1775775
It is proposed for backport to 2.4 but has not yet been applied there.
ApacheLounge has provided fixed binaries for Windows including the
suggested fix. See the discussion at
https://www.apachelounge.com/viewtopic.php?p=34723
