AFAICT, as of PHP 5.3.6, this function doesn't work correctly with any delimiter character other than plain slash (/), which is annoying if your pattern looks like a URL or file path for example (which itself may contain slashes you'll have to escape).

One can make use of the print_r($your_mongoregex_object) statement to ensure the pattern is recognized properly.
