wasm-mutate

[pgarba]

Hi,

I'm playing around with wasm-mutate and noticed that after some iterations it will break the binary.

Error message when loading the wasm file in Firefox:
"wasm streaming compile failed: CompileError: wasm validation error: at offset 398: exported table index out of bounds"

Sometimes it just breaks the code and the returned value is wrong.

Is there any stable version of the tool ? Right now I'm compiling from the master branch.

It's a bug if wasm-mutate creates an invalid module from a valid module. Would you be able to share a test case?
