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.
