Automatic arrays that are not address-taken should not be subject to store data races. This applies to OMP SIMD in-branch lowered functions result array which for the testcase otherwise prevents vectorization with SSE and for AVX and AVX512 ends up with spurious .MASK_STORE to the stack surviving.
Does this also apply for "automatic arrays" as defined by the Fortran Standard (see https://j3-fortran.org/doc/year/23/23-007r1.pdf, page 104), i.e., outside of the OMP_SIMD construct ?
In gfortran, when using the option -fstack-arrays, they are assigned memory space on the stack.
