----------------
I'm getting a crash here when attempting to dereference incomplete c(++) types.
The simplest (albeit contrived) repro is:
```
$ cat /tmp/a.c
struct incomplete;
struct incomplete *var = (struct incomplete *)0xdead;
int main() {}
$ clang /tmp/a.c -o /tmp/a.out -g
$ lldb /tmp/a.out -o "target variable var[0]"
(lldb) target create "/tmp/a.out"
Current executable set to '/tmp/a.out' (x86_64).
(lldb) target variable var[0]
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
backtrace.
Stack dump:
