[Bug fortran/13240] New: wrong alignment of automatic adjustable DOUBLE PRECISION array

["gcc-bug at vogtner dot de" <gcc-bugzilla at gcc dot gnu dot org>]

The base address of a local (automatic) adjustable DOUBLE PRECISION
array ist not properly aligned. Please take a look into the files
enclosed. The program reports:

ADDRESS OF DBLE : BFDFF54C

indicating that the local array is only a multiple of 4 instead
of 8 bytes.

As a workaround a tried -mpreferred-stack-boundary=n for some n.
Only for n = 2 and 3 (in case of GCC 3.2.2 and 3.3.2) and only for n = 2
in case of GCC 2.95.3 the array is correctly aligned.
