The Address sanitizer failure blocking this makes no logical sense. I cannot reproduce it on my systems because an address sanitizer build doesn't even work at all.
Update: Zach Ware pointed out that I also needed to export ASAN_OPTIONS=detect_leaks=0:allocator_may_return_null=1:handle_segv=0 for that run. With that I can get a functioning ASAN build at least, but am still unable to reproduce the issue.
Update 2: You need an ubuntu 20.04 gcc 9.4 based system to reproduce it. anything more modern does not. regardless, the asan failure didn't make sense. I'm having those tests skipped under asan.
