jameysharp commented on issue #5915:

Here's the line where the array index is out of bounds. (The line number is different on current main than in the above stack trace.)
https://github.com/bytecodealliance/wasmtime/blob/3ff3994a1/cranelift/interpreter/src/step.rs#L1578

I don't much like the structure of the loop here, but despite that it looks to me like it ought to work. Interesting!
