Crash when parsing `#pragma omp task` and `[[omp::directive(task)]]` #116258

Gian-Laager · 2024-11-14T16:48:11Z

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:

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.
