From: stas at zend dot com Operating system: Linux PHP version: 5.3.0RC1 PHP Bug Type: Reproducible crash Bug description: ext/filter crashes when module startup bails out
Description: ------------ 1. If one of the modules startup bails out, that leads to aborting the startup sequence and PG(modules_activated) be 0. This, in turn, precludes running RSHUTDOWN functions on modules. 2. ext/filter allocates IF_G(get_array), etc. in the course of the request startup, and if RSHUTDOWN is not called, they are not cleaned up. 3. Since ext/filter does not initialize IF_G arrays, on the next request uncleaned value will be used. Since these arrays are no longer pointing to a valid memory (which was cleaned on the end of the previous request), this will result in a crash. Reproduce code: --------------- 1. Create extension that uses zend_bailout in RINIT. 2. Run two requests while ext/filter is present and turned on 3.
