pessimizing compiler
/pes'*-mi:z`ing k*m-pi:l'r/ [antonym of
`optimizing compiler'] n. A compiler that produces object code that
is worse than the straightforward or obvious hand translation. The
implication is that the compiler is actually trying to optimize the
program, but through excessive cleverness is doing the opposite. A
few pessimizing compilers have been written on purpose, however, as
pranks or burlesques.
