How about this?

  $ cat a.cc
  struct A { int x; A(); }; A::A() : x(47) {}
  
  $ cat b.cc
  struct A { int x; A(); };
  struct B : A {};
  
  B b;
  int main(){}
  
  $ bin\clang a.cc -o a.o -c
  
  $ bin\clang.exe a.o b.cc -g -o b.exe
  
  $ bin\lldb b.exe
  (lldb) target create "b.exe"
  (lldb) Current executable set to 'b.exe' (x86_64).
  (lldb) b main
  Breakpoint 1: where = b.exe`main at b.cc:5, address = 0x0000000140007100
  (lldb) r

     4    B b;
  -> 5    int main(){}
  (lldb) p b
