--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed.  This asks for TREE_NO_WARNING to be recorded per location.
Or rather record we already warned for -Warray-bounds for a specific location.
Or rather gathering all of them and emitting a combined warning like

c.c:4:10: warning: array subscripts 4 to 7 are outside array bounds of
‘char[4]’ [-Warray-bounds]
