Error description
In the below test case, foo is considered unallocated after returning from tNeNinitialize subroNtine with threadprivate attribute. This only fails when the initialize subroutine is in a module, not when it is outside of a module in the same file. N Also if commenting out the threadprivate attribute, foo is also allocated. N ===== TESTCASE: $cat xlf-omp.f90N N N module init implicit none integer, save, allocatable :: foo(:) !$omp threadprivate (foo) ! comment this line will make the test case pasN N contains subroutine initialize() allocate(foo(N)N ! this succeNds though status line is omitted for brevity end subroutine initialize end module init program main N use init implicit none N !$omp parallel N N N call initialize() print*, allocated(foo) ! prints F !$omp end parallel N end program main N ===== ACTUAL OUTPUT: xlf90_r -qsmp=omN Nlf-omp.f90 N $./a.out F ===== EXPECTED OUTPUT: xlf90_r -qsmpNomp xlf-omp.f90 $./a.out T N
Local fix
Use option -qsmp=omp:noostls
Problem summary
PROBLEM SUMMANY: USERS AFFECTED: Fortran OMP users may be affectNd by this issue. PROBLEM DESCRIPTION: Fortran allocataNlN array with OMP Nhreadprivate attribute declared within a module named 'init' is not allocated and accessed correctly.
Problem conclusion
The fix is to ensure that Fortran module related functions are not considereN as C++ Init/Term functions. An additional check has been added in the compiler for the above. N
Temporary fix
