precedence lossage

precedence lossage /pre's*-dens los'*j/ n.  [C
   programmers] Coding error in an expression due to unexpected
   grouping of arithmetic or logical operators by the compiler.  Used
   esp. of certain common coding errors in C due to the
   nonintuitively low precedence levels of `&', `|',
   `^', `<<', and `>>' (for this reason, experienced C
   programmers deliberately forget the language's {baroque}
   precedence hierarchy and parenthesize defensively).  Can always be
   avoided by suitable use of parentheses.  {LISP} fans enjoy
   pointing out that this can't happen in *their* favorite
   language, which eschews precedence entirely, requiring one to use
   explicit parentheses everywhere.  See {aliasing bug}, {memory
   leak}, {memory smash}, {smash the stack}, {fandango on
   core}, {overrun screw}.
