--- Comment #2 from Markus Trippelsdorf <trippels at gcc dot gnu.org> ---
With -Wall one gets:
test.c: In function ‘main’:
test.c:12:14: warning: operation on ‘m’ may be undefined [-Wsequence-point]
D = A[m][B[m++]];
^
Thus your testcase is invalid because of unsequenced modification
and access to m.
