Comment #1 on issue 43449 by evv...@gmail.com: elfutils:fuzz-dwfl-core: Timeout in fuzz-dwfl-core
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=43449#c1
As far as I can see it takes the fuzzer about 15 seconds to process this file without ASan so it doesn't seem to be an elfutils issue.

As one of the comments on this says "it takes the fuzzer about 15
seconds to process this file without ASan so it doesn't seem to be an
elfutils issue".
15 seconds sounds like a very long time, especially without asan. ASAN
often takes a long time on 64bit arches. I would recommend to only use
it on 32bit targets if possible.
However it isn't clear to me what this "fuzz-dwfl-core" is, where the
source is and how to replicate this.
Cheers,
Mark
