I think this issue could be fixed by moving the zend_destroy_rsrc_list(&EG(regular_list)) call after the module shutdown. I've attached a patch demonstrating the principle (this fixes the hashtable destroyed message and I don't get anything bad like a segfault).

But many resource dtors may need some action from modules they belong to. If modules are already past shutdown, that may be a problem. If we must spend time on supporting dl(), then I'd propose to fix module dtor so that it wouldn't try to access EG(regular_list) - if it happens as you described, it doesn't need it anyway. Hi,

This has nothing to do with dl(). mysqli was loaded in php.ini via extension=mysqli.so I can't test the proposed fix until August, but it sounds like it would also fix the issue without messing with shutdown. Greg
