Package: gfortran
Version: 4:5.3.1-1
Severity: important
Tags: upstream

Dear Maintainer,

I am receiving an internal compiler error (ICE) with gfortran when I
try to compile code that initializes an array (pointer or allocatable)
defined inside a datatype with a scalar value. The problem only
happens with the -check=mem flag.

This is a test code that triggers the error:


program test

  type tt
    real(8), allocatable :: aa(:)
  end type tt

  type(tt) :: cc


  cc%aa = 0.0_8

end program test


This is the compilation line:

gfortran -fcheck=mem array.f90

and the error message:


   cc%aa = 0.0_8
internal compiler error: in wide_int_to_tree, at tree.c:1464
0x969524 wide_int_to_tree(tree_node*,
generic_wide_int<wide_int_ref_storage<false> > const&)
0x10ab123 build_int_cst(tree_node*, long)
