Bug #79878 [NEW]: Assertion failure with constexpr attribute and constructor promotion

From: nikic Operating system: PHP version: 8.0Git-2020-07-21 (Git) Package: Scripting Engine problem Bug Type: Bug Bug description:Assertion failure with constexpr attribute and constructor promotion Description: ------------ <?php class Test { public function __construct( <<A(B)>> public $param ) {} } We try to compile attribute A(B) twice. However, constant expression compilation is a destructive process, so this asserts. We should probably only compile once and then copy them from the param to the property.
