Language: new static/self/parent in function compiles — Zend Cannot use "static" when no class scope is active (re-#32227, Zend/zend_compile.c)

Problem

A function (no class scope) that contains new static, new self, or new parent compiles and prints accepted if the function is never called. Zend is a compile-time fatal even when f() is unused:

Cannot use "static" when no class scope is active (same for self / parent).

#32227 (closed) covered static::foo() method-call form via rejectPseudoClassFetchOutsideKnownClassScope(). new lowering (Op\Expr\New_) never calls that helper, so the same illegal program still loads.

Verified 2026-08-18 @ dda76adf48 vs Zend 8.2.32.

Repro	Zend 8.2.32	VM / JIT
function f() { return new static; } echo "accepted";	Fatal Cannot use "static" when no class scope is active	accepted (rc=0)
function f() { return new self; }	Fatal Cannot use "self" when no class scope is active	accepted (rc=0)
function f() { return new parent; }	Fatal Cannot use "parent" when no class scope is active	accepted (rc=0)
function f() { static::foo(); } (control, #32227)	same Zend fatal	VM already compile-aborts

php-src reference

• php/php-src Zend/zend_compile.c — zend_compile_new() → zend_ensure_valid_class_fetch_type() / ZEND_FETCH_CLASS_SELF|PARENT|STATIC with !CG(active_class_entry) → Cannot use "%s" when no class scope is active

PHP implementation target

• lib/Compiler.php Op\Expr\New_::class branch (~line 14792) and compileNewExprForThrow() — before emitting TYPE_NEW, call existing rejectPseudoClassFetchOutsideKnownClassScope() / rejectPseudoClassFetchOutsideKnownClassScope with the class operand keyword (self/parent/static)
• Reuse compileScopeKnowsNoClassEntry() + PseudoClassTypeHintCompileCheck::messageFor() from Language: static::/self::/parent:: method call in function compiles — Zend Cannot use "static" when no class scope is active (Zend/zend_compile.c) #32227
• Same compile path for JIT/AOT; no new runtime/*.c logic

<?php
function f() {
    return new static;
}
echo "accepted\n";

Done when

• VM and JIT compile-abort with Zend substring Cannot use "static" when no class scope is active (never print accepted); same for new self and new parent
• Invoking f() is unnecessary — fatal is at compile, matching Zend
• Language: static::/self::/parent:: method call in function compiles — Zend Cannot use "static" when no class scope is active (Zend/zend_compile.c) #32227 method-call form still compile-aborts
• Compliance .phpt guard under test/compliance/cases/language/
• php-src-strict; no php-compiler-strict shortcut

merged: #32263 (b737697dcb)

Verification

• php bin/vm.php test/repro/maintainer_gap_new_static_no_scope.php → rc=255, Cannot use "static" when no class scope is active (same for self/parent; JIT static repro also rc=255). Never printed accepted.
• ./script/phpunit.sh --filter 'PseudoClassNewCompileFatalTest|PseudoClassNewNoScope32252|PseudoClassCallNoScope32227|PseudoClassStaticCallCompileFatalTest' → OK (29 tests, 58 assertions)
• php script/bootstrap-inventory.php --check → OK 7590/7590

php-src-strict: compile fatal in named free functions via zend_compile_new() / zend_ensure_valid_class_fetch_type() wording. File-level / closures unchanged (runtime inherit/rebind). #32227 method-call form still compile-aborts.
