Alex Crichton ff1ae6e10c Flag another error as ok to hit when fuzzing (#3092)
We've got a lot of fuzz failures right now of modules instantiating
memories of 65536 pages, which we specifically disallow since the
representation of limits within Wasmtime don't support full 4GB
memories. This is ok, however, and it's not a fuzz failure that we're
interested in, so this commit allows strings of that error to pass
through the fuzzer.

Fuzzing Infrastructure for Wasmtime

This crate provides test case generators and oracles for use with fuzzing.

These generators and oracles are generally independent of the fuzzing engine that might be using them and driving the whole fuzzing process (e.g. libFuzzer or AFL). As such, this crate does not contain any actual fuzz targets itself. Those are generally just a couple lines of glue code that plug raw input from (for example) libFuzzer into a generator, and then run one or more oracles on the generated test case.

If you're looking for the actual fuzz target definitions we currently have, they live in wasmtime/fuzz/fuzz_targets/* and are driven by cargo fuzz and libFuzzer.
