I'm also seeing this on PHP 5.4.12, for what it's worth.
Program terminated with signal 11, Segmentation fault.

Full backtrace at http://web2.jaredsmith.net/core.6360.backtrace.txt,
and core file at http://web2.jaredsmith.net/core.6360.backtrace.txt.
Again, if a PHP developer is interested in looking more closely, I'm happy to help facilitate
access to a server.
