The following program is presumably invalid (I have not checked the standard).
ifort and sunf95 reject it with:
warning #6755: A COMMON block data object may not have the SAVE attribute.
ERROR: Object "I2" has the SAVE attribute, so it must not be equivalenced to an
object in a common block.
Ad hoc I don't see why it is only a warning and not an error with ifort.
(g95, gfortran, NAG 95 accept it without warning.)
integer :: i1, i2
common /block/ i1
save i2
equivalence(i1,i2)
end
