The following bounds problem is not detected with gfortran at compile time (it
is at run time):
integer,allocatable :: a(:)
integer :: b(1)
allocate(a(12))
b = a(1:12)
end
Expected: The same output as NAG f95 has:
Error: a.f90, line 4: Different vector lengths (1 and 12)

How do I get:
pr36754.f90:4.1:
b = a(1:12)
1
Error: Different shape for array assignment at (1) on dimension 1 (1 and 12)
? I don't have that many patches left.

Hmm, I currently get the same (with all gfortrans I have). I really wonder why
I did not get this before. Let me recheck tomorrow.

Same thing here.
What doesn't raise a warning, but could, is
integer,allocatable :: a(:)
integer :: b(1)
allocate(a(12))
b = a
end

I get an error at compile time with gfortran 4.2.3, 4.3.3, 4.4.0, and trunk
(intel-darwin9). Is this PR valid?

Good question - I get now the same error for comment 0, which makes the report
INVALID<already implemented since a long time>.
I don't get an error for comment 4. I think it is in principle detectable, but
difficult -> WONTFIX?
At run time, I get for comment 4 "(0/11)" instead of the proper "(1/12)", but I
think the off-by-one bug is tracked elsewhere.

Confirmed. It may already be in one (or several) opened PR in the [meta]
PR27766. I have started to look at it, but it is quite messy.

This may be a duplicate of PR36683(?).

The off-by-one bug is fixed.

laptop:kargl[287] ./z

Fortran runtime error: Array bound mismatch, size mismatch for dimension 1 of

Can we close this PR?
