This is due to a typo in:

2008-04-20  Thomas Koenig  <tkoenig@gcc.gnu.org>

         PR libfortran/35960
         * intrinsics/reshape_generic.c (reshape_internal): If the size
         of the resized array is zero, as determined by the SHAPE
         argument, return early.
         * m4/reshape.m4:  Likewise.

This is because the following:

       if (rextent[n] < 0)
         rextent[n] == 0;

should be:

       if (rextent[n] < 0)
         rextent[n] = 0;

Apparently, intrinsics/reshape-generic.c is not subject to that same  
issue.
