you appear to have .pdb symbols for your php. Now you need them for apache...

#2 0x00002aaaac145afb in apr_pool_destroy () from /usr/lib64/libapr-1.so.0 No symbol table info available.

See http://httpd.apache.org/dev/debugging.html on how to grab the -win32-symbols.zip package. Unpack it over httpd and you will probably have more legible backtraces. Ensure you have all the debugging symbols for php you'll have something completely legible.
