I created some experimental tool called Avalanche which was a king of a fuzzer
based on Valgrind.
But that was already quite a long time ago.
You can still have a look

it struck me that the Valgrind execution environment could be used to write a
fuzzer that could discover changes in flow of control in response to variations
in input files, and thus provide a better feedback mechanism than "Load a file,
see if the test program
crashes".
