Re: [Patch, fortran] PR108889 -[12/13/14/15 Regression] (Re)Allocate in assignment shows used uninitialized memory warning with -Wall if LHS is unallocated

[Andre Vehreschild]

Hi Paul,

isn't the ref you are computing here:

+      /* Mark so that rhs "used unallocated" warnings can be issued.
  Component
+        references do not generate the warnings.  */
+      for (ref = expr1->ref; ref; ref = ref->next)
+       if (ref->type == REF_COMPONENT)
+         break;

not the same you compute before the outer if? I see at least no change
to it in between.

I haven't tested your patch yet, but will do when I have some grid
power for my notebook. I am wondering what happens, when one uses a
coarray here.

Thanks for the patch.

Regards,
        Andre
