Weird behaviour in "Locals and Watchers" window with std::vector<bool>

"Locals and Watchers" window in Qt Creator displays wrong information about std::vector<bool> instances while debugging. For example when I initialize instance of vector<bool> to 50 trues, only first 32 items show true and rest show false. Also when I create instance of vector<bool> with 65 items, inspecting shows it has only 33 items. The instances of vector<bool> are actually correct, only reporting in "Locals and Watchers" window is broken. Here is minimal example which reproduces this bug:

#include <vector>

int main(void)
{
	std::vector<bool> v1(50, true);
	std::vector<bool> v2(65);

	return 0; // breakpoint here
}
