Lines 359 to 363 in 44c052b

	static unsigned int const c_nMaxHeight = std::conditional<
	(random_level_generator::c_nUpperBound <= skip_list::c_nHeightLimit),
	std::integral_constant< unsigned int, random_level_generator::c_nUpperBound >,
	std::integral_constant< unsigned int, skip_list::c_nHeightLimit >
	>::type::value;

Inside conditional minimum value is choosen, and in random_level max is bounded with 32. But, array index will be initialized with greater number from conditional. So it is possible to have array of 32 elements and index 99.
Possible resolution is to add assert or use min value from conditional for index
