It crashed. I'll go ahead and create 29 more fuzzers to see how it goes. @yevgenypats it seems Fuzzit thinks the fuzzer timed out even though MSan complained about "MemorySanitizer: use-of-uninitialized-value". Could you take a look at https://app.fuzzit.dev/orgs/RxqRpGNXquIvqrmp4iJS/targets/fuzz-unit-file-msan/l59lm5xOfbV4yUxmvwHf? |

I'm not sure who else apart from @mrc0mmand and me receives notifications from Fuzzit but given that it's most likely going to be a bumpy ride, I'm sorry in advance. |

In principle it seems to be ready to roll but I guess now it would make sense to switch to a new organization on Fuzzit we were talking about recently mostly to get rid of those ids. @yevgenypats I'll reach out to you via Slack tomorrow. |

Now that the ids are gone, we can generate commands simply using names as we go

I'll go ahead and merge the PR so that we can move the resources from the old organization to the new one. After that I'll launch a cron job on Travis CI to finish the migration. |

It's just a follow-up to systemd#13281 that should make it a little bit easier to make sense of MSan reports. https://clang.llvm.org/docs/MemorySanitizer.html#origin-tracking
