Bug #: 54990
Summary: [4.8 Regression] [OOP] ICE in tree_operand_check on
SELECT TYPE
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: ja...@gcc.gnu.org
CC: abenso...@gmail.com
Reported by Andrew Benson at
http://gcc.gnu.org/ml/fortran/2012-10/msg00094.html. Reduced test case:
program test
implicit none
type :: ncBhStd
end type
type :: tn
class (ncBhStd), allocatable, dimension(:) :: cBh
end type
type(tn), target :: a
select type (q => a%cBh(1))
end select
end
Compiles cleanly with 4.7, but trunk gives the following ICE:
internal compiler error: tree check: expected class ‘expression’, have
‘declaration’ (var_decl) in tree_operand_check, at tree.h:4109
program test
