For the illegal code
integer, allocatable :: ivec(:)
print*,"shape(ivec)=",shape(ivec)
end
gcc version 4.3.0 20070315 (experimental)
gfortran -W -Wall -pedantic-errors -std=f2003 -fbounds-check -Werror
xshape_alloc.f90
gives
shape(ivec)= 4298784
It would be nice if a run-time error message about the use of array that has
not been allocated were emitted. A fairly common mistake I make is to pass an
array that is allocatable in the caller, before having
allocated it, to a procedure as an argument which is
not allocatable. Within the procedure, applying SIZE
or SHAPE will give strange results.

------- Comment #1 from burnus at gcc dot gnu dot org 2007-03-22 22:32 -------
This is related to 29616 (same for nullified pointers). As the test is
essentially the same, I added a comment there and close this PR as duplicate.
Thanks for the idea though it will likely take a while until it will be
implemented.
*** This bug has been marked as a duplicate of 29616 ***
