------- Comment #1 from burnus at gcc dot gnu dot org 2007-08-22 06:36 -------
Minimal example:
implicit none
real, TARGET :: a(0:100)
real, pointer :: p(:)
p => a
print *, lbound(a), ubound(a)
print *, lbound(p), ubound(p)
end
Prints:
0 100
1 101
instead of (ifort, NAG f95, g95):
0 100
0 100
"7.4.2.1 Data pointer assignment"
"If no bounds-remapping-list is specified, the extent of a dimension of
data-pointer-object is the extent of the corresponding dimension of
data-target. [...] the lower bound of each dimension is the result of the
intrinsic function LBOUND (13.7.60) applied to the corresponding dimension of
data-target. The upper bound of each dimension is one less than the sum of the
lower bound and the extent."
