[Bug fortran/27229] New: char_transpose_1.f90 fails with ICE in gfc_conv_array_transpose

["janis at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Test gfortran.dg/char_transpose_1.f90 fails on mainline for
powerpc-unknown-linux-gnu with optimization:

/home/gccbuild/gcc_trunk_anonsvn/gcc/gcc/testsuite/gfortran.dg/char_transpose_1.f90:9:
internal compiler error: in gfc_conv_array_transpose, at
fortran/trans-array.c:726^M

A regression hunt identified this patch:

        * local-alloc.c (rest_of_handle_local_alloc): Use VEC instead
        of VARRAY.
        * reload1.c (reg_equiv_memory_loc_varray): Rename to
        reg_equiv_memory_loc_vec.  Change the type to VEC(rtx,gc) *.
        (init_reload, reload): Use VEC instead of VARRAY.
        * reload.h: Update the prototype for
        reg_equiv_memory_loc_varray.

That seemed unlikely so I tried reverting that patch from today's mainline, and
it did indeed allow the test to pass.

The same ICE is reported in PR26119, filed 2006-02-06.
