Wasmtime GitHub notifications bot (Jun 15 2026 at 19:52): Wasmtime GitHub notifications bot (Jun 15 2026 at 19:52):alexcrichton opened PR #13659 from alexcrichton:fix-host-leak to bytecodealliance:main:
This commit fixes issues in the implementation of futures and streams for component-model-async where when a guest dropped its half of a future/stream connection, and the other half was owned by the host, then the host-owned half would be leaked within the store.
This is similar in spirit to #13515 but has a smaller test and additionally takes into account some review comments.
Closes #13515
