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.
Rainer

Created attachment 28443
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=28443
Reduced testcase
The dse2 dump reads:
dse: local deletions = 0, global deletions = 1, spill deletions = 0
starting the processing of deferred insns
deleting insn with uid = 25.
ending the processing of deferred insns
but the memory location stored to
(insn 25 27 154 2 (set (mem/c:SI (plus:DI (reg/f:DI 30 %fp)
(const_int 2039 [0x7f7])) [6 A.1+16 S4 A64])
(reg:SI 1 %g1 [136])) array_constructor_4.f90:4 61 {*movsi_insn}
(nil))
is read by a subsequent call to memcpy.
