Issues

• Fused adapters skip Canonical ABI validation traps: unaligned pointers, invalid char, out-of-bounds strings

  pulseengine/meld#586 · Filter by author avrabe opened on Nov 8, 2026

• latin1+utf16 → latin1+utf16 strings are copied verbatim, not deflated: valid output, wrong answer

• Fused-output samples for loom's fused optimizer (semantics proof + behavioral differential)

  pulseengine/meld#568 · Filter by author avrabe opened on Nov 7, 2026

• parser: map<K,V> is classified as P3Async (latent mislabel, unreachable while CM_MAP is off)

  pulseengine/meld#567 · Filter by author avrabe opened on Nov 5, 2026

• wasm32-wasip3 inputs: fused code bypasses __wasm_task_hook, so the stack pointer in context slot 0 is never set

• test: spec-derived WAST for new Component Model features

• ci: make the wasmtime differential oracle required

• ci: fuzz is informational; pinned component-model tests never run

• p3: async lowering of a world-level func import drops the [async-lower] marker (sibling of #557)

• future/stream read and write lowered through wit-component's shim stay unresolved as actual::N imports, with exit 0

• Fused output renames a host-bound [async-lower]f import to plain f, so the name no longer says the call is async

• P3 sync→async trampoline uses an outdated waitable-set-poll ABI, writes at address 0, and picks the wrong component's import

• Stream/future built-ins are bound by the core module's own import name (a hand-written name can bind the wrong built-in)

  pulseengine/meld#552 · Filter by author avrabe opened on Nov 4, 2026

• --component does not work for P3 inputs (2 of 504 give a valid component)

  pulseengine/meld#549 · Filter by author avrabe opened on Nov 3, 2026

• P3 pairs: async cross-component calls stay host imports (30 of 47 pairs)

• Parser enables only CM_ASYNC: threading, async-builtins, stackful and error-context components are refused at parse

• P3: fusion exits 0 with an invalid module (11 of 504 corpus components)

• Untraced caller lower falls back to the calling module's own realloc, which can be the wrong allocator

• Sync transcoding adapter does not handle string results: invalid module at exit 0

  pulseengine/meld#522 · Filter by author avrabe opened on Oct 22, 2026

• Import map: determinable dtor reported as null; misleading 'unknown' reason under --memory shared

  pulseengine/meld#520 · Filter by author avrabe opened on Oct 22, 2026

• An optional-argument copy over a flat-ABI i64-joined slot produces an invalid module at exit 0

• Adapter copies call realloc with alignment 1 instead of the element alignment
