Just to note that this has (finally!) fixed the last asan failure in the mach-o lld code. The first passing results are <a href="http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux-fast/builds/11308" rel="noreferrer" target="_blank">http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux-fast/builds/11308</a><br>
<br>
We still have to fix the ubsan failures which look to be the same issue over and over again, and i’ll work on that next.<br>
<br>
Cheers,<br>

PS, sorry this took so long. I really hoped to have something in place at the end of last week but it took longer than expected to get my head around the YAML parser and its interaction with owning pointers.<br>
