abrown opened issue #3140:

@alexcrichton suggested moving to use log_wasm to output the contents of fuzzed WebAssembly modules instead of printing them to stdout or log::debug as is done currently. There are some advantages to doing this, mainly it is very convenient to run the Wasm file in wasmtime directly or upload it somewhere. Any opinions on this, @fitzgen? If we all agree then I will do this refactoring after #3124 is resolved.

I would only add that this should only be done when debug logging is enabled, so that we aren't doing a bunch of file I/O on every iteration by default.

Yeah, that's a good point. I also saw a few cases in there where we log when something goes wrong--should we do both?

Yeah, we just want to make sure not to do any file I/O on the typical, error-free paths.
