[Bug fortran/31194] NaN transfer - internal compiler error: in gfc_conv_constant

[burnus at gcc dot gnu dot org]

--- Comment #1 from burnus at gcc dot gnu dot org  2007-03-16 09:34 ---
I'm not anymore sure whether it is valid or not.

Related:
   NaN = transfer(ishft(int(z'FFF8',8),32),0.0_8)
this prints duly NaN with NAG f95, sunf95, ifort, g95 and gfortran.

The example of comment 0 prints NaN with g95 and sunf95, ifort prints 0.0
(???) and NAG f95 rejects it with:
Error: foo.f90, line 1: INT of non-integer not permitted in an initialisation
expression
which somehow looks strange.

Yet another transfer bug :(

Reduced testcase:
  real :: NaN = transfer(0,0)
  print *, NaN
  end
