Stdlib: stream_context_set_options() inline array literal — $options arrives null (ext/standard/streams.c)

Problem

stream_context_set_options($ctx, ['http' => ['timeout' => 1]]) fatals: Argument #2 ($options) must be of type array, null given.

Passing the same array via a variable works. Inline array literals are not lowered to the second argument.

Related umbrella: #3448 — this is the concrete inline-literal repro.

php-src reference

• php/php-src ext/standard/streams.c — php_stream_context_set_options
• php/php-src ext/standard/basic_functions.stub.php — PHP 8.4 stream_context_set_options

Repro

test/repro-maintainer/parity_stream_context_set_options_inline.php

<?php
declare(strict_types=1);
$ctx = stream_context_create();
stream_context_set_options($ctx, ['http' => ['timeout' => 1]]);
$got = stream_context_get_options($ctx);
echo 'timeout=', ($got['http']['timeout'] ?? 'missing'), PHP_EOL;

./script/docker-exec.sh -- bash -lc 'source script/php-env.sh
php bin/vm.php test/repro-maintainer/parity_stream_context_set_options_inline.php'

Form	Zend (8.4+)	VM today
Inline array literal 2nd arg	OK	TypeError: … null given ❌
Variable holding array	OK	OK ✅

Implementation hints (PHP-in-PHP)

• Likely named-arg / call lowering bug for internal builtins — check compile path for stream_context_set_options in lib/Compiler.php and ext/standard/stream_context_set_options.php.
• Runtime merge logic already in ext/standard/VmStreamContext.php — fix argument materialization, not C.

Done when

• Inline-literal repro green under VM
• Regression guard in compliance or unit test
• Named-parameter variants from Stdlib: stream_context_set_option / get_options / get_params / set_default (ext/standard/streams.c parity) #3448 still tracked separately

Merged via #15709.

Root cause: supportsStreamContextSetOptions() gated on CompilerVersion::VERSION (8.4.0-dev) instead of languageProfileVersion(), so PHP_COMPILER_PROFILE=8.4 never registered the builtin — inline-literal calls could not be exercised. Lowering was already correct once registered.

Fix: Gate on languageProfileVersion() (same pattern as supportsFpow()).

Verification (Docker):

• PHP_COMPILER_PROFILE=8.4 php bin/vm.php test/repro-maintainer/parity_stream_context_set_options_inline.php → timeout=1
• CompilerVersionGateTest forward/reference profile tests — OK
• VMTest stream_context_set_options_inline.phpt — OK
