This should have already been reported, but I cannot find any trace of it.
gcc.dg/Warray-bounds.c fails on all the platforms I have looked at:
FAIL: gcc.dg/Warray-bounds.c (test for warnings, line 59)
FAIL: gcc.dg/Warray-bounds.c (test for warnings, line 65)
FAIL: gcc.dg/Warray-bounds.c (test for warnings, line 66)
where the wernings are missing for the above lines. This can be traced to
revision 131502:
PR middle-end/32135
* tree-ssa-ccp.c (maybe_fold_offset_to_array_ref): Do not construct
references above array bounds. This might trigger bounds checks for
pointers to arrays.
