These testcases were segfaulting:
prefix
director_using_member_scopes
virtual_poly
The fix here is admittedly a hack - we perform the initialisation
of EG(class_table) from CG(class_table) which PHP will do, but
hasn't yet.
PHP doesn't seem to clearly document which API calls are actually
valid in minit or other initialisation contexts, but the code we're
generating works with all PHP 7.x and PHP 8.x versions aside from PHP
8.0 so it seems this is a bug in PHP 8.0 rather than that we're doing
something invalid, and we need to work with existing PHP 8.0 releases
so this hack seems a necessary evil. It will at least have a limited
life as PHP 8.0 is only in active support until 2022-11-26, with
security support ending a year later.
Fixes#2383.
Fix access to already released memory during PHP module shutdown, which
often didn't cause visible problems, but could result in segmentation
faults, bus errors, etc. Fixes#1170, reported by Jitka Plesníková.
PHP5's C extension API has changed substantially so you need to use
-php7 to specify you want PHP7 compatible wrappers.
