I'm running the full tests on AARch64 and the only RT test that fails is:<br>
<br>
UndefinedBehaviorSanitizer-Standalone :: TestCases/Float/cast-overflow.cpp<br>
<br>
The problem seems to be a trap in __sanitizer::internal_memchr() while<br>
trying to handle __ubsan::__ubsan_handle_float_cast_overflow().<br></blockquote><div><br></div><div>Can you give more info (exact report, gdb trace, etc)</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">
