Problems
Memory allocation routines fill guard bytes with values that are not supposed to be used by the programmer's algorithms. This is, however, not predictable. When the algorithm uses those values and overwrites the guard bytes with them (only the last write before deallocation is relevant), the overflow can not be detected, because the bytes have not actually changed. Instead, the memory breakpoint option can be used, set on a condition of access to those bytes in a debugger.

Famous quotes containing the word problems:
“We have heard all of our lives how, after the Civil War was over, the South went back to straighten itself out and make a living again. It was for many years a voiceless part of the government. The balance of power moved away from it—to the north and the east. The problems of the north and the east became the big problem of the country and nobody paid much attention to the economic unbalance the South had left as its only choice.”
—Lyndon Baines Johnson (1908–1973)
“Sustained unemployment not only denies parents the opportunity to meet the food, clothing, and shelter needs of their children but also denies them the sense of adequacy, belonging, and worth which being able to do so provides. This increases the likelihood of family problems and decreases the chances of many children to be adequately prepared for school.”
—James P. Comer (20th century)
“I have a horror of people who speak about the beautiful. What is the beautiful? One must speak of problems in painting!”
—Pablo Picasso (1881–1973)
