Agreed. I haven't actually tested the patch though but since it's
covered by the fuzz
target it should be tested once it's merged anyway.

On a somewhat related looking at some recent patches and especially
https://sourceware.org/git/?p=elfutils.git;a=commit;h=64ee2cb792e7b6ba6ad2a5759bff7ce8714e4668
it seems apart from OSS-Fuzz elfutils is fuzzed elsewhere. Aleksei I
wonder if it would
be possible to add those fuzz targets to OSS-Fuzz? There are blind
spots there and I think it would be
really great to start covering at least some of them.

Thanks,
Evgeny Vereshchagin
