See below: I've provided enough backtrace I think to figure out what is going on here, but I'm trying to figure out the type of `loweredExpr`, but it causes a crash in the `getContext`.
Args:
```
(gdb) show args
Argument list to give program being debugged when it is started is "-fc1 -fopenacc flang_parallel_self.f90 -emit-fir -o -".
```
Soruce of that file is:
https://godbolt.org/z/aaEd4oxWj
```
(gdb) p loweredExpr.getType().dump()
Program received signal SIGSEGV, Segmentation fault.
mlir::Dialect::getContext (this=0x7fffffff18a8cc) at /local/home/ekeane/llvm-project/flang/../mlir/include/mlir/IR/Dialect.h:52
52 MLIRContext *getContext() const { return context; }
The program being debugged was signaled while in a function called from GDB.
GDB remains in the frame where the signal was received.
To change this behavior use "set unwindonsignal on".
Evaluation of the _expression_ containing the function
(mlir::Type::dump() const) will be abandoned.
When the function is done executing, GDB will silently stop.
