<br>
I've seen this issue pop up on the mailing list a couple of times<br>
before with no resolution [1][2][3].<br>
<br>
It has been getting really bad for our AArch64 buildbots lately. You<br>
can see a few examples at the end of my email [4], but we have the<br>
same failures on a couple of other bots as well.<br>
<br>
Does anyone have any idea how to reproduce / investigate these issues?<br>
If not, is it reasonable to mark the tests as unsupported on AArch64?<br></blockquote></div></div></blockquote><div><br></div><div>I think that's fine, although AFAIK, these tests are very stable on x86, right?</div></div></div></blockquote><div><br></div><div>Correct. </div><div>Last time I've checked, some of the libFuzzer tests</div><div>were very slow, and thus flaky, due to lsan/aarch64 being very slow. </div><div><a href="https://github.com/google/sanitizers/issues/703">https://github.com/google/sanitizers/issues/703</a><br></div><div><br></div><div>--kcc </div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div style="overflow-wrap: break-word;"><div><div><br></div><div>Kuba</div><br><blockquote type="cite"><div><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
