Both PHP4 and Pike has a function called do_exit. They do different things (TM). The result of this name clash is that Pike exits if die/exit is used in a PHP4 script.
I have attached two patches (for 7.0 and 7.1) which replaces do_exit with pike_do_exit. A similar report has been sent to the PHP4 people.
