MemoryManager mm = MemoryPoolLite(smpl);
void* p;
char* c;
ASSERT_TRUE(mm);
p = NULL;

EXPECT_TRUE(p);
p = NULL;
p = mm.allocate<int>();
EXPECT_TRUE(p);
c = NULL;
c = reinterpret_cast<char*>(mm.calloc(10));
EXPECT_EQ(10L, count(c, c+10, '\0'));
c = NULL;
c = reinterpret_cast<char*>(mm.calloc(5, 7));
EXPECT_EQ(35L, count(c, c+35, '\0'));
static const string c_example = "Hello World";
