lldb crash repro

  $ cat /tmp/a.cc
  #include <vector>
  
  void f(std::vector<int>& v) {
          *(volatile int*) nullptr = 0;
  }
  $ cat /tmp/main.cc
  #include <vector>
  
  void f(std::vector<int>& v);
  
  int main() {
          std::vector<int> v ;
          f(v);
  }
  $ ./build/bin/clang++ -g /tmp/a.cc -o /tmp/a.so -shared -stdlib=libc++ -fuse-ld=lld -Wl,-rpath,$PWD/build/rel/lib
  $ ./build/bin/clang++ -g /tmp/main.cc /tmp/a.so -o /tmp/a -stdlib=libc++ -fuse-ld=lld -Wl,-rpath,$PWD/build/rel/lib
  $ ./build/bin/lldb /tmp/a -b -o run
  # crash

any help with adding a test case for this would be appreciated, I'm not sure if there's any testing for shared libraries in lldb?
