Crash reproducer for lldb version 10.0.0 (git@github.com:apple/llvm-project.git revision 3093af41dd65ad466dcd5603e9289244edfee4f5)

Swift version 5.3.3 (swift-5.3.3-RELEASE)

 

Reproducer written to '/tmp/reproducer-a515ea'
 

Before attaching the reproducer to a bug report:

 - Look at the directory to ensure you're willing to share its content.

 - Make sure the reproducer works by replaying the reproducer.

 

Replay the reproducer with the following command:

lldb -replay /tmp/reproducer-a515ea

@adrian-prantl just to be sure that these reports have all the info you need. If not, is there anything else you’d need apart from the reproducer?
