A reghunt revealed that this was caused by this patch:

2012-06-06  Richard Guenther  <rguenther@suse.de>

        PR tree-optimization/53081
        * tree-data-ref.h (adjacent_store_dr_p): Rename to ...
        (adjacent_dr_p): ... this and make it work for reads, too.
        * tree-loop-distribution.c (enum partition_kind): Add PKIND_MEMCPY.
        (struct partition_s): Change main_stmt to main_dr, add
        secondary_dr member.
[...]

It already occurs with a non-bootstrap gfortran and is independent of the
libgfortran.so (built with our without the patch) used.

I'm attaching the assembler outputs.
