/* This is a standalone program that loads every file specified
* as a command-line argument, and runs LLVMFuzzerTestOneInput
* on this data. This function is normally called by libFuzzer
* for every input it generates. This standalone program
* makes it possible to run just a specific input or inputs.
*
* This is necessary if you want to test your input files
* with MemorySantizer, because libFuzzer doesn't work well
* with MemorySanitizer.
*
* Code inspired by:
* https://github.com/openssl/openssl/blob/master/fuzz/test-corpus.c
