This does not seem to happen with

❯ R -d lldb
(lldb) target create "/Library/Frameworks/R.framework/Resources/bin/exec/R"
[...]
(lldb) run
[...]
Process 52551 launched:

    0x10002c9f8 <+20>: retq
(lldb)

So maybe this is a bug in the R shell wrapper then? I am not sure, but
it would be nice to make 'R -d lldb' work out of the box.

Thanks,
