Re: [Bug libfortran/46182] New: Run time check for invalid use of unallocated allocatable variables

It would be nice to have a run time check for such invalid use of unallocated allocatable variables (such as -fcheck=use_unalloc). If you use an unallocated variable you get a segmentation fault. Isn't this a sufficient runtime check ?
