[Following up, now that I'm actually subscribed to this distribution list]
I've filed bug https://bugs.php.net/bug.php?id=65338 to track this issue. The
root cause of the AV is when more than one module hooks the interned strings, a
"wrong" value will be left in CG(interned_strings_start), which the Zend core
thinks contains the value that it alloc'd during zend_interned_strings_init().
More details are in the bug.
I've added a potential fix for the Zend folks to consider. It's slightly less
harsh than the workaround provided by Jan. ;)
Thx!
