Bug description:Access violation if extension can't be loaded

Description:
------------
Only TS builds are affected.

Assuming this in my "php.ini:
| extension = "nonexistent.dll"

is resulting in a crash.

(6cc.1260): Access violation - code c0000005 (first chance)
First chance exceptions are reported before any exception handling.
This exception may be expected and handled.

ds:0023:0802fb80=????????


BTW:
Using "dl('nonexistent.dll');" in a script is working as expected. Also
with NTS builds there is no problem.


Test script:
---------------
in the shell:
php -v

Expected result:
----------------
| Warning: PHP Startup: Unable to load dynamic library
| 'C:\Program Files\PHP\php-current\ext\nonexistent.dll'

Or no error with "display_startup_errors = Off"

Actual result:
--------------
CLI has stopped working
