--- Comment #6 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Some bound issues were fixed with PR99043 =E2=80=93 but my bet is that the =
BIND(C)
issues still exist. (=E2=86=92 testcase (C + Fortran) attached to this PR).

 * * *

Additionally: PR 94020 (duplicate of this PR) with attachment 47960 seems t=
o be
mostly fixed, however for the following case, the result is wrong.

if 'lb' (or second argument to 'foo') is >=3D 0, size2 =3D=3D 0 =E2=80=93 o=
therwise, size2 >
0'.

Expected:
   same result as for PRODUCT(SHAPE(ARRAY,KIND))
   (=E2=86=92 16.9.179  SIZE (ARRAY [, DIM, KIND]))
That is:
  lb =3D   5 =E2=86=92 shape =3D [5 -1] =E2=86=92 -5
  lb =3D -12 =E2=86=92 shape =3D [5 - 1] =E2=86=92 -5

implicit none
integer :: A(5,5)
call foo(a,-12)
call foo(a,0)
call foo(a,5)
contains
subroutine foo(x,lb)
  integer :: lb
  integer :: x(5,lb:*)
  print *, size2(x)
  if (size2(x) /=3D -5) stop 1
end
integer function size2(y)
  integer :: y(..)
  size2 =3D size(y)
end
end=
