ci: cross-arch streflop determinism gate - #10
Merged
Conversation
Build tools/sync-test on ubuntu (SSE) and macOS (NEON), then assert bit-identical results — the multiplayer guarantee that Apple-Silicon agrees with gcc/x86. Runs on push to main and on PRs touching determinism-relevant paths (streflop, sse2neon, FastMath.h, the test), plus workflow_dispatch. Fork-specific so it does not collide with the upstream-derived streflop-float-test.yml (which is x86-only, manual, and needs submodule init to run).

* Improve USE_ASAN configuration for all build types - Remove restriction to DEBUG builds only - ASAN works well with optimized builds - Add -fPIC for shared library compatibility with ASAN - Add -fno-omit-frame-pointer for better stack traces in error reports - Add -fno-optimize-sibling-calls to preserve full call chains - Set -O2 optimization level for better error detection than -O3 - Add explanatory comments for each flag 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> * Fix stack-use-after-scope in TextureCreationParams Replace std::initializer_list with std::array in wrapModes field. std::initializer_list is just a view into a temporary array, so storing it as a member variable creates a dangling pointer once the temporary is destroyed.

The issue occurred when a Lua event handler called SetInnerRML, which destroyed elements and triggered OnDetach callbacks. OnDetach immediately deleted the listener with "delete this", but ProcessEvent was still on the call stack trying to invoke the Lua callback. The fix defers deletion by: 1. Setting m_detached flag in OnDetach instead of immediate deletion 2. Checking the flag at the start of ProcessEvent (handles queued events) 3. Checking the flag at the end of ProcessEvent (handles mid-execution detachment) This ensures the listener object is only deleted when it's safe to do so, after all its methods have returned.

When called from Lua for render-to-texture workflows, PushLayer/PopLayer would execute outside the frame lifecycle, causing the layer stack to underflow and access freed memory. Solution: Wrap the Lua binding for Context::Render with a lambda that calls BeginFrame before and PresentFrame after rendering, ensuring proper layer stack management for all callers including RTT use cases.

Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> * Fix heap-use-after-free in Element::SetClass via deferred deletion When a Lua event handler calls element.inner_rml = "...", it destroys all child elements. If Lua holds references to those children and tries to use them later in the same event handler (e.g., calling SetClass), it causes a use-after-free. Solution: Wrap SetInnerRML in the Lua binding to manually remove children and store them in a deferred deletion list. Children are kept alive until the event processing completes, preventing use-after-free when Lua accesses them.

Adds a fork-specific workflow that builds the streflop float test on x86_64 (SSE) and arm64 (NEON) and asserts bit-identical results — the multiplayer determinism guarantee for the macOS fork. Supersedes the upstream streflop-float-test.yml (x86-only, manual, broken without submodule init). Opening this PR primarily to run the new CI and verify it goes green before landing on main.
