This feature is used "classic" Fortran 77 libraries such as Starpac, as
mentioned in comp.lang.fortran on 23-Apr-2007 .

c:\fortran> type d1mach.f90
function d1mach(i)
implicit none
double precision d1mach,dmach(5)
integer i,large(4),small(4)
equivalence ( dmach(1), small(1) )
equivalence ( dmach(2), large(1) )
data small(1),small(2) / 0,   1048576/
data large(1),large(2) /-1,2146435071/
d1mach = 0.0d0
end function d1mach

[Bug fortran/31672] Not Implemented: Initialization of overlapping variables

Thanks for reporting this -- this is a rather nicer testcase than the one we
had for this already.

I've also changed the title of PR #29786 to make it easier to find.

*** This bug has been marked as a duplicate of 29786 ***

BTW - The fix for 29786 is awaiting completion of Brooks' struggles to get the
necessary gcc patches committed for simplify_transfer.  The moment that
infra-structure is in place, I can fix overlapping initializers; the patch has
already been tested.
