I have "LogLevel warn". (That line is the same as in default httpd.conf file).

I cannot build the Windows binaries.

I reproduced this with a simple configuration:
I created a repository with binaries and configuration at GitHub:
https://github.com/kkolinko/test_20161222

Configuration:
- defaults
- change listen address and port number (127.0.0.1:9090)
- change listen address in Tomcat (127.0.0.1)
- enable mod_proxy, mod_proxy_ajp
- configure proxying for examples webapp.

Reproduction:
- Start servers
- Browse to http://127.0.0.1:9090/examples/
- Refresh the page (F5), If it matters, the browser is Firefox 50.1.0


Notes:
1.Running the reproducing recipe from
https://github.com/kkolinko/test_20161222 on Windows 10:

- There is no "send crash report to MS" dialog, but the crash line in
the log and response delay are the same.
- The exit code mentioned in the log is different:
AH00428: Parent: child process 4576 exited with status 3221225477 -- Restarting.
- I am closing server consoles with Ctrl+C. There is some oddity
following "Apache server interrupted..." line in error.log.
The text is mangled, as if two processes are trying to write to the
same log file.

2. Running HTTPD on Windows 7 as a service, there is notable delay
when I stop the service.
