Hi, this is causing a regression on the greendragon x86_64 lldb bot, it took a little while to repo and narrow down today.  https://green.lab.llvm.org/green/view/LLDB/job/lldb-cmake/ is failing on TestDequeFromStdModule.py, I can repo it on an intel mac.  We're crashing under

@Michael137 might be better able to understand the nature of the regression, I'm not very familiar with this part of llvm, I'm trying to get repo steps for him on an aarch64 mac to build & run it under translation.  I think we'll need to revert this until we can figure out the failure.
