I receive the following ICE:
transferbug.f90: In function ‘bucketindexofkey’:
transferbug.f90:14: internal compiler error: in gfc_get_element_type, at
fortran/trans-types.c:741

when compiling this test code:

module InternalCompilerError

   type Byte
      private
      character(len=1)                                  :: singleByte
   end type

contains

   function BucketIndexOfKey(key) result (hash)
      type(Byte), intent(in)                            :: key(:)
      integer                                           :: hash
      integer, parameter                                :: intPrototype(1) = 0
      integer                                           :: intKey(
size(transfer(key, intPrototype)) )
      intKey = transfer(key, intPrototype)   ! This line causes the ICE
      hash = 0
   end function

end module

program main
   use InternalCompilerError
end program


The ICE seems to disappear when removing the following line, which makes me
think that it is the direct cause:

      intKey = transfer(key, intPrototype)   ! This line causes the ICE


Regards,
Drew McCormack

I'd say it's a duplicate of PR31193, which was fixed on 2007-03-22. At least,
your testcase doesn't trigger the bug on i386-linux nor on x86_64-linux.
Closing as duplicate: could you try it with an updated compiler (maybe download
it from http://gcc.gnu.org/wiki/GFortranBinaries, as I recently uploaded a new
MacOS/powerpc package) and reopen the PR if the bug is not fixed for you?

*** This bug has been marked as a duplicate of 31193 ***
