I'm running libfuzzer for PHP source code and I have results NEW_FUNC. As I understand it shows uncovered "features".

NEW_FUNC[1/1]: 0xaaaab50687f8 in zend_hash_packed_grow /php-src/Zend/zend_hash.c:312
I want to get the test case for this trace, however with the files named like 0aaea2b53ceef682d7eb2dbe0a27f20ba8f3ca24 it's not clear to me where I should look and I have over 20k such files created. Is this even feasible to find or that's not the purpose of libfuzzer?
