That's r262912/commit 0d7f90652080c42cddca6f9b68f6895218c70880
"PR middle-end/82063 - issues with arguments enabled by -Wall":

| --- gcc/c-family/c.opt
| +++ gcc/c-family/c.opt
| [...]
|  Warray-bounds
| -LangEnabledBy(C ObjC C++ LTO ObjC++,Wall)
| +LangEnabledBy(C ObjC C++ LTO ObjC++)
|  ; in common.opt
|
|  Warray-bounds=

OK to push the attached "options: Remove
'gcc/c-family/c.opt:Warray-bounds' option definition record"?
