PHP Bug Type: Reproducible crash
Bug description: Crash when constructor called inappropriately (statically)
Description:
------------
PHP 5.2.x (tried 5.2.1, 5.2.0) crashes if a constructor is called
statically from within the host class.
Code explains this better.
I realize I'm not SUPPOSED to do this, but I did it accidentally (I made a
mistake). I expect the error message. It shouldn't, however, crash.
Reproduce code:
---------------
php -r 'class Foo { private function __construct() { } function get() {
self::__construct(); } } Foo::get();'
Expected result:
----------------
E_FATAL
Here's 5.1.6:
Fatal error: Non-static method Foo::__construct() cannot be called
statically in Command line code on line 1
In 5.2.0, this was downgraded to E_STRICT, which I suspect is why it
crashes (E_FATAL would have bailed, E_STRICT tries to run this messed up
code).
Actual result:
--------------
here's the backtrace:
(gdb) run -r 'class Foo { private function __construct() { } function
get() { self::__construct(); } } Foo::get();'
Starting program: /usr/local/bin/php -r 'class Foo { private function
__construct() { } function get() { self::__construct(); } } Foo::get();'
