[R-SIG-Mac] incompatible lldb on mojave?

[Bob Rudis]

Can you provide a bit more info on the setup?

I ask b/c: (more below the snippet)

    $ R -d lldb
    (lldb) target create "/Library/Frameworks/R.framework/Resources/bin/exec/R"
    Current executable set to
'/Library/Frameworks/R.framework/Resources/bin/exec/R' (x86_64).
    (lldb) run
    Process 3834 launched:
'/Library/Frameworks/R.framework/Resources/bin/exec/R' (x86_64)

    R version 4.0.0 RC (2020-04-21 r78267) -- "Arbor Day"

    R is a collaborative project with many contributors.
    Type 'contributors()' for more information and
    'citation()' on how to cite R or R packages in publications.

    Type 'demo()' for some demos, 'help()' for on-line help, or
    'help.start()' for an HTML browser interface to help.
    Type 'q()' to quit R.

I have full Xcode installed and updated to latest (I'm on developer betas).

    $ lldb --version
    lldb-1103.0.17
    Apple Swift version 5.2 (swiftlang-1103.0.22 clang-1103.0.22)

I'm also on a more restrictive OS (Catalina).

Of note: macOS prompted me for permission to use lldb.
