I have a similar problem, running php.exe (Version 5 beta 4) from the commmandline (Windows XP). 

Enabling php_exif.dll in php.ini makes php crash, without it everything is fine. Other extensions such as php_gd2.dll are working fine. I have no previous versions of PHP installed.

Are you using mbstring extension? If not load it and try again.

Yes, mbstring is added. Without php_exif all is fine. 

If I dont have php_exif.dll in the root of the php folder php appears unable to find it, even though it is with all the other extensions and can find them.

this is the error I get :

This application has failed to start because php_mbstring.dll was not found. Re-installing the application may fix this problem.

followed by:

PHP Startup:Unable to load dynamic library 'c:/php/ext/php_exif.dll' - The specified module could not be found.

I can confirm this bug.

I'm downloading the php5-win32-latest.zip daily and use it with apache1.3 and apache2.

Since the release of beta 3, all versions were always crashing while loading the php_exif.dll (even if php_mbstring.dll was also loaded) unless php_exif.dll was copied in the php5apache.dll directory (in my case the php5 dir).

After some further experiments using PHP 5.0.0 snapshots in the command prompt.

Loading php_exif.dll results in an error "php_mbstring.dll was not found". Loading php_mbstring.dll works just fine. Loading both php_exif.dll and mbstring.dll results in "php_mbstring.dll was  not found".

Next, copying the php_mbstring.dll to the php.exe root results in a php crash when loading php_exif.dll.

Please try this:

php.ini:
extension=php_mbstring.dll
extension=php_exif.dll

NOTE: the order is important.

If that doesn't work, try modifying your PATH to
include the PHP extension dir, then try again.

php-cgi.exe works!

php.ini excerpt :

extension=php_mbstring.dll
extension=php_exif.dll

So I guess loading php_mbstring has to be done prior to loading php_exif.

This should be documented somewhere..

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
