The subject line gives a pretty good idea what this question is
about. Yes, I'm well aware of the dangers of making core changes, and
I'm only doing it to give myself a better idea what's going on
inside :). In any case, here's the problem...
One of the changes I tried to make is changing the type of the
track_errors setting from zend_bool to long. It seems like a simple
enough change: change the type in php_globals.h, update the INI
setting in main.c, update the actual usage of the var in main.c,
update my local INI file to use an integer value.
But as soon as I did this, my test build started showing leaks from
php_hash_environment() and a crash in php_module_shutdown()-
>php_shutdown_ticks()->zend_llist_destroy(). My only guess as to why
it was happening is that I didn't change a type or expected size
somewhere, but for the life of me I can't figure out where my mistake
was; I haven't seen a harcoded size where sizeof() should be or
anything like that, after poring through main.c, php_variables.c,
zend_globals.h, php_globals.h, and the like.
I've reverted my source, but I'd still like to know: What did I miss?
TSRM was on (--enable-maintainer-zts), as was --enable-debug, if that
helps. I didn't try it without TSRM; if I can't do it thread-safely,
then I'm not doing it right regardless.
