Phar PHPTs intermittently crash with O+ in accel_startup about zendoptimizerplus HOT 7 OPEN

I am now also having this same crash running these PhpUnit tests from the Symfony framework on Apache on Windows using O+ 7.0.1-dev (from March 14th):

With 5.5.0beta1 and opcache, I am now intermittently getting the same crash with these PHPTs:
ext/date/tests/bug48058.phpt
ext/date/tests/timezone_identifiers_list_wrong_constructor.phpt
ext/standard/tests/class_object/is_a_variation_002.phpt

from zendoptimizerplus.

I do not think it has something to do with VC11 but only that the code runs faster/better, creating better conditions to reach some hard to reproduce bugs (concurrency, bad access, etc.).

from zendoptimizerplus.

In 5.5-rc6e911e, these PHPTs also reproduce this crash:
tests/classes/clone_006.phpt
ext/session/tests/session_set_save_handler_class_005.phpt

from zendoptimizerplus.

@mattficken Same backtraces using all tests?

from zendoptimizerplus.

Yes same backtrace

from zendoptimizerplus.

With 5.5.0beta4-x64, these 2 PHPTs can also repro this issue:
ext/gmp/tests/035.phpt
ext/gmp/tests/036.phpt
