Bug #69876 [NEW]: scalar typehint crash if default value is not related type

From: dams Operating system: OSX & Debian PHP version: 7.0.0alpha1 Package: Reproducible crash Bug Type: Bug Bug description:scalar typehint crash if default value is not related type Description: ------------ With the new scalar typehint, when providing a default value with another type, PHP crashes. function a(int $a = 1.2) {} $a is supposed to be an integer, and the provided default value is a float. I checked this on the last rev of php-src (d9d1948396285583a915018fe9310fad998876ca, Thu Jun 18 17:22:22 2015 +0200), both on Debian 8 and Osx 10.10 Test script: --------------- <?php function a(int $a = 1.2) {} // sh: line 1: 49762 Segmentation fault: 11 php70 -l sth.php 2>&1 // Will also crash with the following : /* function a(int $a = true) {} function a(int $a = "3") {} function a(int $a = array()) {} function a(string $a = 1.2) {} function a(string $a = true) {} function a(string $a = array()) {} function a(string $a = 4) {} function a(string $a = -1) {} function a(float $a = true) {} function a(float $a = "3") {} function a(float $a = array()) {} function a(float $a = 4) {} function a(float $a = -1) {} function a(bool $a = 1.2) {} function a(bool $a = "3") {} function a(bool $a = array()) {} function a(bool $a = 4) {} function a(bool $a = -1) {} */ ?> Expected result: ---------------- Don't crash. Emit an error message at linting time to prevent such error.
