Description
This is an issue from Fujitsu testsuite.
The execution of a program compiled by flang-new terminates with a fatal error.
In the program, a temporary array is made in the if clause.
If the condition in if clause is replaced with another temporary variable, the error doesn't occur.
The following are the test program, Flang-new and gfortran execution result.
! test.f90
program omp
integer(4),dimension(2,2)::a
a=reshape((/-1,0,1,2/),(/2,2/))
call sub(a)
end program
subroutine sub(a)
integer(4),dimension(2,2)::a
!$omp parallel if(any(a/=reshape((/-1,0,1,1/),(/2,2/))))
!$omp end parallel
!$omp parallel if(any(a/=reshape((/-1,0,1,1/),(/2,2/))))
!$omp end parallel
end subroutine$ flang-new -v test.f90 -fopenmp
