Bug ID: 68020
Summary: Issue with implied-shape array parameter of rank > 2
Product: gcc
Version: 5.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gerhard.steinmetz.fort...@t-online.de
Target Milestone: ---
Based on f2008 (5.3.8.6), an implied-shape array is declared with
an implied-shape-spec-list. This works excellent for rank 1 and 2,
but is rejected for higher ranks.
$ cat z2.f90
program p
integer, parameter :: a(1, 2) = 0
integer, parameter :: x(*, *) = a
integer, parameter :: y(11:*, 12:*) = a
integer :: k
do k = 1, 2
print *, k, lbound(x, dim=k), ubound(x, dim=k)
print *, k, lbound(y, dim=k), ubound(y, dim=k)
end do
end
$ gfortran z2.f90
$ a.out
1 1 1
1 11 11
2 1 2
2 12 13
