Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc.

If possible, make the script source available online and provide
an URL to it here. Try avoid embedding huge scripts into the report.

Every mysqli query crash.

The call to zend_parse_method_parameters at line 620 in ext/mysqli/mysqli.c will result into mysql_result = NULL.

mysql_result get passed to zend_object_store_get_object and he will crash because the parameter must not be NULL.
