Description:
------------
Memory corruption on 64bit oses.

On 32bit systems sizeof(long)=4 bytes, but on 64bit systems sizeof(long)=8 bytes.
When using zend_parse_parameters() "l" modifier, the receiving argument must be long, not int.
Here is the patch that fixes these issues:

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