I do not know how this bug is linked to others (e.g. 18883), I let you decide.
It was on GNU Fortran 95 (GCC 4.0.0) and is still in the 4.1 snapshot I build 
yesterday (gcc-4.1-20050826).

I get a ICE on that file (cutils.f95): (!==== lines are part of the file) The 
reported function is 'inttochar2' althoug the reported line is 7 (which is the 
line public::IntToChar2).

[:prompt:] cat cutils.f95
!================
module cutils
  implicit none
  private
   
  integer :: maxStringLength = 25
  public :: IntToChar2
contains
 
  elemental function IntToChar2(integerValue)
    integer,              intent( in) :: integerValue
    character(len = maxStringLength)  :: IntToChar2
    !
    !   Creates the character representation of an integer.
    !
 
    write(IntToChar2, *) integerValue
  end function IntToChar2
   
end module cutils
