------- Comment #1 from burnus at gcc dot gnu dot org 2009-01-15 20:04 -------
Confirm. This is a regression with regards to 4.2.1; it fails at least since
20071008 (my oldest 4.3 trunk version).
Thanks for the report!

------- Comment #2 from burnus at gcc dot gnu dot org 2009-01-15 20:10 -------
ida = lbound(a%i)
if (any(ida /= (/1,1/))) print *, 'lbound ', ida
Here, gfortran prints:
lbound 0 2
Correct would be
lbound 1 1
ida = ubound(a)
>>>>>>>>>>>>>>>>>>>^^^
Here a "%i" is missing otherwise the following line does not make sense:
if (any(ida /= (/6,7/))) print *, 'ubound ', ida
For ubound(a) the result should be "5 8" which is also gfortran's result.
For ubound(a%i):
gfortran: 5 8
correct: 6 7

Too late - the release is too soon (freeze; release-candidate build is
running). Regarding 4.4.0: Do you plan to submit a patch soonish?
