FYI:
I can't repro this on Windows with the build off the snaps' box (VC9
x86 Non Thread Safe (2009-Aug-18 16:00:00)).
It:
blocks until connection using telnet[expected]
doens't consume any CPU[expected]
and returns 'bool(false)' [expected -- I assume the same as
'int(0)']
and exits[expected]

This makes a serious security issue. It is a very effective DoS on
all single process PHP servers with SSL and a slightly less bad DoS on
multi-process PHP servers.

Bug is in ext/openssl/xp_ssl.c
Function handle_ssl_error: (line 107)
case SSL_ERROR_WANT_READ:
case SSL_ERROR_WANT_WRITE:
/* re-negotiation, or perhaps the SSL layer needs more
* packets: retry in next iteration */
errno = EAGAIN;
retry = is_init ? 1 : sslsock->s.is_blocked; //BUG
break;
it sets retry to 1 in php_openssl_enable_crypto no matter if socket is
blocking or not.
