The miscompilation appears first with -O -ftree-vrp, i.e. removing -ftree-vrp
from the following command line gives a working executable, with it, we get a
broken compiler.

The generated code emitted for the TRANSPOSE for i386-darwin is stupid:
atmp.13.dtype = parm.12.dtype;
atmp.13.dim[0].stride = parm.12.dim[1].stride;
atmp.13.dim[0].lbound = parm.12.dim[1].lbound;
