Hi Puyan,<br>
<br>
I failed to reproduce with <a href="http://llvm.org/master" rel="noreferrer" target="_blank">llvm.org/master</a> (5faa533e47b0e54b04166b0257c5ebb48e6ffcaa <<a href="https://reviews.llvm.org/rG5faa533e47b0e54b04166b0257c5ebb48e6ffcaa" rel="noreferrer" target="_blank">https://reviews.llvm.org/rG5faa533e47b0e54b04166b0257c5ebb48e6ffcaa</a>>) on Ubuntu 18.04.1 LTS both in debug and release build.<br>
<br>
Since it sounds like you can reproduce "reliably" - can you please share more info how to reproduce?<br>
