--- Comment #6 from Martin Sebor <msebor at gcc dot gnu.org> ---
Reconfirming with GCC 10 and 11.  The output for the test case in comment #2
is:

pr86889.c: In function ‘d’:
pr86889.c:8:13: warning: array subscript -1 is below array bounds of ‘long
int[2]’ [-Warray-bounds]
    8 |     if (p->b[g])
      |         ~~~~^~~
pr86889.c:1:17: note: while referencing ‘b’
