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: unassignedclangb...@nondot.org
Reporter: jdoerf...@anl.gov
CC: andrey.churba...@intel.com,

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;
}
}
