            Bug ID: 45047
           Summary: Captured variables stored twice into task
           Product: OpenMP
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Clang Compiler Support
          Assignee: unassignedclangbugs at nondot.org

In the following simple example we store A twice into the task structure
(https://godbolt.org/z/Wq9xx6). The second time is especially problematic since
we use the hardcoded 40 byte offset from the `task_alloc` return instead of
loading the `shared` pointer value (first in the task struct).

void foo(int *A) {
    #pragma omp task
    {
        *A = 0;
    }
}
