A pretty serious bug crept into 4.3.5.
A few weeks ago, a TSRM fix was commited which was supposed to prevent memory leaks when PHP ends its execution (shutdown dtor was not being called in tsrm_shutdown()). This fix causes a crash when a shared extension registers a dtor function. This is because the dtor is called after the extension is unloaded. Stas has commited a patch to TSRM which prevents the dtor call for now, which isn't very important because besides giving a warm fuzzy feeling, it's right before PHP shuts down and thus, memory leaks aren't important anyway. On a side note the per-thread dtor is still called, thus, eliminating leaks when threads are created/destroyed in multi-threaded servers.
I suggest we release 4.3.5pl1 with just this bug fix within the next couple of days as this is a crash bug which can happen on any MT server or MT-safe PHP builds (such as Windows CGI).
