CID 899327:         Incorrect expression  (UNINTENDED_INTEGER_DIVISION)
Dividing integer expressions "this->m_adaptive_sigma_stride" and "this->m_pace", and then converting the integer quotient to type "double". Any remainder, or fractional part of the quotient, is ignored.

336 size_t x = cvm::ceil(m_adaptive_sigma_stride / m_pace);
