ICEs when compiling the following testcase, extracted from
flang/test/Evaluate/errors01.f90 from the flang 14.0.3 test suite:
module m
contains
subroutine s5
logical, parameter :: mask(2,3) = reshape([.false., .true., .true.,
.false., .false., .true.], shape(mask))
integer, parameter :: field(3,2) = reshape([(-j,j=1,6)], shape(field))
integer :: x(2,3)
x = unpack([1,2], mask, 0)
end subroutine
end module
