On *-apple-darwin9 with gfortran 4.5.0 or 4.4.1, the following code gives at
-O2:
! { dg-do compile }
subroutine foo
implicit none
integer :: i
call gee_i(int(i**huge(0_8),kind=kind(i)))
! call gee_i(int(i**(-huge(0_8)-1_8),kind=kind(i)))
end subroutine foo
gives at -O2:

virtual memory exhausted: Cannot allocate memory

The code compiles with values other than huge(0_8) or with gfortran 4.3.
