No idea why script crashes. I'm including my compile information and the backtrace.

I hav recompiled with minimal extensions compiled in, namely: ./configure \ --disable-all \ --with-pcre-regex \ --prefix=/usr/local/php/${PHP_VERSION_DIR}/installation \ --exec-prefix=/usr/local/php/${PHP_VERSION_DIR}/installation And I still have a no go. I spent the last 3 hours trying to produce a short script which would illustrate the bug and running the PHP binary through GDB and Valgrind to no avail. What I do know is that at: zend_do_declare_property (/usr/local/php/php5-200312120830/Zend/zend_compile.c:2442) CG(active_class_entry) evaluates to null and so CG(active_class_entry)->ce_flags causes a NULL pointer fault. I tried patching with a test for NULL, but then I got a crash in zend_hash_find() where the memory for the hash appeared to be corrupted - Valgrind was not useful in determining where the memory may have become corrupt. I was going to set up a link to an InterJinn download, but while I was testing to make sure it ran, I got the following error (possibly related to this bug): <b>Fatal error</b>: Only variables or references can be returned by reference in <b>/home/suds/yackspit/interJinn-0.9.1/Core/libraries/templateJinn/templateManager.inc</b> on line <b>17</b><br /> For which the actual line of code is: var $filename = __FILE__; which is in a class. If it is also helpful I get a LOT of deprecated warnings for: <b>Strict Standards</b>: var: Deprecated. Please use the public/private/protected modifiers. The reason I think maybe the above is related is because in the backtrace of the original report, and more recent ones with minimal extensions, the zend_do_declare_property() function is attmepting to work with a property called "filename".
