ICE on valid code. Might be related to PR 18769.
Taken from PR 29471 comment 5.
real(kind(0d0)) :: NaN = transfer(ishft(int(z'FFF80000',8),32),0d0)
print *, NaN
end
gives:
foo.f90:1: internal compiler error: in gfc_conv_constant, at
fortran/trans-const.c:348

------- 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'FFF80000',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
