Actually I can hit this issue also with sh4 and microblaze. The test
program needs to be modified slightly:

int main(void)
{
        char *p;
        if(1) {
                char i[48];
                p = __builtin_alloca(8);
                p[0] = 1;
        }
        if(1) {
                char i[48] , j[64];
                j[52] = 0;
        }
        return !p[0];
}
