[Bug fortran/41043] New: [4.4/4.5 Regression] virtual memory exhausted: Cannot allocate memory

[dominiq at lps dot ens dot fr]

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:

[ibook-dhum] f90/bug% time gfc -O2 integer_exponentiation_2_db_red.f90
virtual memory exhausted: Cannot allocate memory
28.270u 4.114s 1:27.92 36.8%    0+0k 0+11io 282pf+0w

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