--- Comment #2 from janus at gcc dot gnu.org 2012-10-10 08:11:59 UTC ---
While trying to reduce it, I found a version which also ICEs with trunk:
implicit none
type treeNode
type(treeNode), pointer :: right => null()
end type
type(treeNode), pointer :: theNode
print *, associated( RightOf(theNode) )
contains
function RightOf( theNode )
class(treeNode), pointer :: RightOf
type(treeNode), target, intent(in) :: theNode
RightOf => theNode%right
end function
end
Apparently, the ICE on the original test case was only prevented by the error
message mentioned by Dominique.
With 4.8 trunk one gets the following output:
CompilerBug.f03:10:0: internal compiler error: in fold_convert_loc, at
fold-const.c:1979
