I'm also seeing this on PHP 5.4.12, for what it's worth.
Program terminated with signal 11, Segmentation fault.
#0 0x00007fce6f4635b9 in gc_zval_possible_root (zv=0x7fce7e2cbbd8)
at /usr/src/debug/php-5.4.12/Zend/zend_gc.c:143
143 GC_ZOBJ_CHECK_POSSIBLE_ROOT(zv);
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.

I'm seeing this as well, on PHP 5.3.3 on RHEL 6.4 using Drupal as the main web
application. See https://bugzilla.redhat.com/show_bug.cgi?id=915138 for more
details, including links to core files, backtraces, etc.
Also, if a developer would like direct access to a server to help debug, I'd be
willing to help facilitate access.

At first look, I was thinking to a regression introduced by fix for #63635, but
reverting the fix doesn't resolve the issue.
Full traceback, php 5.4.10:

Full traceback, php 5.4.11:

Short traceback, php 5.4.11 with lot extension disable:

Sorry to not being able to produce a simple reproducer, but I could easily
create a test build and ask the initial reporter to test it.
