We want to be in the same global state each time we come in FuzzerTestOneInput(). There are various reasons why we might not be that include: - Initialization that happens on first use. This is mostly the RUN_ONCE() things, or loading of error strings. - Results that get cached. For instance a stack that is sorted, RSA blinding that has been set up, ... So I try to trigger as much as possible in FuzzerInitialize(), and for things I didn't find out how to trigger this it needs to happen in FuzzerTestOneInput().
