Alex Crichton 33312c5380 Fix a possible panic with null-containing element segments (#4455 ) This commit fixes an issue with the initialization of element segments when one of the elements in the element segment is `ref.func null`. Previously the contents of a table were accidentally initialized with the raw value of the `*mut VMCallerCheckedAnyfunc` which bypassed the "this is initialized" encoding of function table entries that Wasmtime uses for lazy table initialization. The fix here was to ensure that the encoded form is used. The impact of this issue is that a module could panic at runtime when accessing a table element that was initialized with an element segment containing a `ref.null func` entry. This only happens with imported tables in a WebAssembly module where the table itself was defined on the host. If the table was defined in another wasm module or in the local wasm module this bug would not occur. Additionally this bug requires enabling the reference types proposal for WebAssembly (which is enabled by default) due to the usage of encodings for null funcrefs in element segments.		2 years ago
