After an unmodified (debug) build (using VC6.0) of PHP4.04 and running the following script 

<?php
$link = mysql_connect ("localhost", "username", "pw");
?>

PHP crashes with an access violation. I tracked this down to an uninitialized mysql.default_socket pointer.

I can solve this problem by setting the STD_PHP_INI_ENTRY (in php_mysql.c) from OnUpdateStringUnempty to OnUpdateString (see below), even though I think this setting was not put there by accident... so I don't know if there are any side-effects (esp for *nix builds)

PHP_INI_BEGIN()
    [...]
    STD_PHP_INI_ENTRY("mysql.default_socket", NULL, PHP_INI_ALL, OnUpdateString, default_socket, zend_mysql_globals, mysql_globals)
PHP_INI_END()

Cheerio, Marc.
