--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Both are guarded like

  p->a0[0] = 4; p->a0[1] = 5;  // { dg-warning "\\\[-Wstringop-overflow"
"pr102706" { target { vect_slp_v2hi_store_align && { !
vect_slp_v4hi_store_unalign } } } }

the vect_slp_* predicates according to comments implement exactly the case in
the testsuite, but for some reason it doesn't work on hppa?

Yes, I guess this implies a problem with

# Return the true if target support vectorization of 4-byte short stores
# with 4-byte aligned address at plain O2.
proc check_effective_target_vect_slp_v2hi_store_align { } {
     set pattern {add new stmt: MEM <vector\(2\) short int>}
     set macro "TEST_V2HI_2"
     return [check_cached_effective_target vect_slp_v2hi_store_align {
         expr [check_vect_slp_store_usage $pattern $macro ] }]
}

# Return the true if target support vectorization of 8-byte short stores
# with unaligned address at plain O2.
# NB: This target should be removed after real issues are fixed for
# -Wstringop-overflow with O2 vect. Be careful if you want to reuse
# this target since tests in check_vect_slp_store_usage
# is the exact match of relative testcases
proc check_effective_target_vect_slp_v4hi_store_unalign { } {
     set pattern {add new stmt: MEM <vector\(4\) short int>}
     set macro "TEST_V4HI"
     return [check_cached_effective_target vect_slp_v4hi_store_unalign {
         expr [check_vect_slp_store_usage $pattern $macro ] }]
}
