Narrowed down to:
program x09f95
    use plf95demolib
    integer, parameter :: nptsx=35, xdim=99
    real(kind=8)   :: xg1(xdim), distort
    xg1 = foo (arange(0,nptsx) / dble(nptsx-1), distort)
contains
elemental real(kind=8) function foo( coord, factor )
    real(kind=8), intent(in) :: coord, factor
    foo = 1
end function foo
end program x09f95

Already filed upstream as PR 52059.  So closing as a dup.

As it is sometimes difficult to find duplicates, you don't have to feel sorry.
In any case, thanks for the bug report and reduced test case.

But the downstream bugreport from which this has been filed already referenced
the PR52059 bug.
