This is a quick/simple reproduction: {{{ DllCall(0, ""int"", ""Function"", ""int"", 0, ""int"", 0) }}} If we use """" (empty string) instead of 0 (or even -1 will crash) in the file name, then it will not crash. This can happen when user will call UDF function that relies on Dll name from global variable, as it happens with _GDIPlus_* UDFs if the user doesn't set _GDIPlus_Startup().
