Description

It would be nice to fuzz the format string parser, although it's not designed to parse untrusted data (format strings should really be literals), it would be nice to have some piece of mind. Also fuzzing could help make our error messages better.

It's not completely clear how this should work, what fuzzer to use, how to integrated it into the test harness, and if we should try and make it apply to llvm's format implementation as well.

Research direction

Start with the format string parser identified in the issue. Determine which fuzzer and test-harness integration are appropriate, and whether LLVM's format implementation is in scope. Done means the parser is fuzzed through the chosen harness and the resulting error-message improvements are covered.
