--- Comment #2 from Nicholas Krause <xerofoify at gmail dot com> ---
Changing i equal to 1 in the second function gives the warning and gets similar
GIMPLE like this to the first function:
<bb 2> [local count: 1073741824]:
i_3 = MAX_EXPR <i_2(D), 1>;
_1 = &a + i_3;
__builtin_memset (_1, 0, 99); [tail call]
return;
Are we assuming somewhere that zero size offsets should for the first argument
of __builtin_memset to be forgotten about? Because I tried it with multiple
numbers other than zero and they all worked to get GIMPLE similar to the above.
