Unicode-rs coverage build fails

[Manishearth]

https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=37516

Step #5: Running unicode-segmentation-fuzzer
Step #5: warning: /workspace/out/coverage/dumps/unicode-segmentation-fuzzer.3547862932440866716_0.profraw: Unsupported instrumentation profile format version
Step #5: error: No profiles could be merged.

I'm not quite sure what's going on here, is this perhaps an issue with how oss-fuzz uses rust? cargo fuzz works fine, and I'm not quite sure how the coverage stuff is being done here.

I think it's related to this issue: #6268

[maflcko]

Is this still an issue now that #6268 is closed?

[Manishearth]

I'll try to wait for the autofiled bug to get closed by the robot before closing this, imo.

Still broken:

Step #5: warning: /workspace/out/libfuzzer-coverage-x86_64/dumps/unicode-segmentation-fuzzer.13117700142267093511_0.profraw: invalid instrumentation profile data (file header is corrupt)
Step #5: error: no profile can be merged

Just fixed by #6551

Thanks! And the issue did self close
