Crash when it encounters this `#pragma`
```
#pragma omp task
{
leftNode =
build_up_quad_tree_split(maxDepth - (splitDir == SplitDir::Y),
leftBodies,
switch_split_dir(splitDir),
numBodiesThreshold);
}
```
if I remove the pragma it compiles just fine, but the same/similar crash also happens with the `[[omp::directive(task)]]` syntax.
Here's the full stdout:
```
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
