+++ This bug was initially created as a clone of Bug #38095 +++

In trying to reduce the ICE, Mikael Morin actually found a different ICE:

------- Bug #38095 Comment #8 From Mikael Morin 2008-11-12 22:43 -------

I tried to reduce the case. 


module bar
implicit none
contains
!
elemental function trim_append(xx,yy) result(xy)
character (len=*), intent(in) :: xx,yy
character (len=len(xx) + len(yy)) :: xy
xy = xx // yy
end function trim_append
!
function same(xx) result(yy)
character (len=*), intent(in) :: xx(:)
character (len=len(xx))       :: yy(size(xx))
yy = xx
end function same
!
subroutine xmain()
character(len=2) :: c(1)
c =  trim_append(["a"],same(["b"]))
end subroutine xmain
!
end module bar

I bet some of you guys recognize that old friend of ours, PR31610, whose patch
was reverted in PR37903.
Of course characters are a special (understand: not working) case. Argh!

This is probably unrelated to the original ICE though.

Spurious - wrong PR number.
