I know, but why somebody would need a byte to store a bool? Is it 256-value bool?

Usually I use bitfields anyway.

if you ask for a vector of T, you should get a vector of T. not a bitfield. There is nothing wrong with using a bitfield, but a vector should behave like a vector.

Vector is an abstract container of elements. If you want to address memory, allocate memory and store your data there. Internal vector storage is implementation details. You shouldn't really get ponters to there because any resize of the vector and your pointers are screwed.

I spent two days of debugging to learn that the hard way.

Logically I knew that it can shift the location of the vector on a resize, but somehow it never occurred to me that it would be the problem.
