            Bug ID: 60796
           Summary: Missing error message in Directive parsing portion of
                    module
           Product: Apache httpd-2
           Version: 2.4.25
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Core
          Assignee: bugs@httpd.apache.org

reproducer

If I return an error in my directive parsing code of module during the second
pass , the error message is never logged. I've attached a module that
reproduces this issue. Here are reproduction steps and steps on how to spot the
error message being logged out incorrectly:

# apxs -i -a -c mod_test.c
# echo IntoTheVoid >> /usr/local/apache2/conf/httpd.conf
# /usr/local/apache2/bin/apachectl -f /usr/local/apache2/conf/httpd.conf -k
start 
 [Wed Mar 01 16:17:34.993411 2017] [intothevoid:error] [pid 14151:tid

139904119781248] AH11111: Test: B

But, if you strace, we can see the error messages being written out to nowhere
in second pass. 

# strace -Tttvfs  1024 -e write /usr/local/apache2/bin/apachectl -f
/usr/local/apache2/conf/httpd.conf -k start

The lack of error output in second pass makes it difficult to troubleshoot
configuration issues without the use of external tool like strace.
