Description:
------------
In php_zip_add_from_pattern() a pointer to file_stripped_len is passed
to php_based which treats the address as a size_t. If the size of int
differs from the size of size_t then this could cause a memory access
error.

int entry_name_len,file_stripped_len;
...

php_basename(Z_STRVAL_PP(zval_file), Z_STRLEN_PP(zval_file), NULL, 0,
   &basename, (size_t *)&file_stripped_len TSRMLS_CC)
