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:
“Men decide far more problems by hate, love, lust, rage, sorrow, joy, hope, fear, illusion, or some other inward emotion than by reality, authority, any legal standard, judicial precedent, or statute.”
—Marcus Tullius Cicero (106–43 B.C.)
“The three great problems of this century, the degradation of man in the proletariat, the subjection of women through hunger, the atrophy of the child by darkness.”
—Victor Hugo (1802–1885)
“Currently, U.S. society has been encouraged by its political and subsidized mass-media intelligentsia to view U.S. life as a continual “morning in America” paradise, where the only social problems occur in the inner cities. Psychologists call this denial.”
—Ishmael Reed (b. 1938)
