He is on the list, but a bit busy I would say.

the second frame address is

  $ addr2line.exe -e /usr/bin/cygwin1.dll 0x6100846A
/usr/src/debug/cygwin-2.1.0-1/winsup/cygwin/dcrt0.cc:1041

       cygwin_exit (user_data->main (__argc, newargv, *user_data->envptr));

so it seems that the process initialization went wrong.
Have you tried to reinstall httpd ?
May be the file was damaged
It should be

2015-07-19 19:43      754717 usr/sbin/httpd.exe

The first address 65DC5D78 seems over the cygwin area.

Cheers
Marco
