Analysing a case where reachable functions are missing from "Reached by Fuzzers"

[sg3-141-592]

I've been analysing some of the situations where the "Reached by Fuzzers" numbers are coming up short, i.e.
(https://storage.googleapis.com/oss-fuzz-introspector/croniter/inspector-report/20230709/fuzz_report.html)).

[oss-fuzz : croniter : 2023-07-09](https://[storage.googleapis.com/oss-fuzz-introspector/croniter/inspector-report/20230709/fuzz_report.html]

Taking an example croniter.get_current(), when it's called it's renamed

@classmethod
def match(cls, cron_expression, testdate, day_or=True):
    cron = cls(cron_expression, testdate, ret_type=datetime.datetime, day_or=day_or)
    td, ms1 = cron.get_current(datetime.datetime), relativedelta(microseconds=1)

And shows up in the callgraph files as fuzzerLogFile-fuzz_match.data.

    cron.get_current croniter 835

This coverage isn't getting matched up with fuzzerLogFile-fuzz_match.data.yaml on the other end, I'm guessing because the names don't match up.

I'm currently working my way through how the report generation works to see where the "Reached by" gets dropped. Any ideas on the right place to look next much appreciated.

Thanks for identifying the issue!

This is most commonly the case!

I'll try and look at this tomorrow!
