alexcrichton opened PR #12882 from alexcrichton:fix-fact-length-calculation to bytecodealliance:main:

This fixes a calculation when the source memory and destination memory have different pointer sizes. A typo meant that the destination byte length used the source byte length by accident instead of the source length. This isn't actually reachable at all in wasm today because memory64 isn't available at this time for components. FACT was originally written with memory64 support, however, to be a bit more future-proof and the component model may be getting memory64 support soon. For now though there's no test for this, just a minor update.
