Latest LLDB under Linux doesn'r report variable values.

With self compile of the latest LLVM/Clang/LLDB, LLDB (12.0.0) fails at a breakpoint while trying to display the current variable values. The processing wheel spins indefinitely and the following is displayed in a panel at the top of the main window:
