Replaced the file as you requested, restarted Apache and running the
file from CLI and Apache still crashed PHP. I was able to generate the
following backtrace, seems to be different from the others (run 3 others
before it to compare all and this is the only different one, as
expected):

Can you replace the libenchant.dll with libenchant_52841.zip, restart
apache and try again please?
http://windows.php.net/downloads/qa/test/libenchant_52841.zip
Also please try using the CLI as well.

Description:
------------
Whenever I try to call (the undocumented function)
enchant_broker_get_dict_path before enchant_broker_set_dict_path my PHP
instance crashes.
My php.ini contains the following entries:
enchant support enabled
Version 1.1.0
Libenchant Version 1.5.0 or later
Revision $Revision: 298870 $
ispell Ispell Provider C:\PHP\libenchant_ispell.dll
myspell Myspell Provider C:\PHP\libenchant_myspell.dll
Test script:
---------------
<?php
$broker = enchant_broker_init();
enchant_broker_get_dict_path($broker, ENCHANT_ISPELL);
?>
Expected result:
----------------
Either false because no dictionary path is set yet or an empty string or
some kind.
Actual result:
--------------
