I observed a code clone from the following files.

function : mpd_qresize @ (file: "Python-3.3.0a2/Modules/_decimal/libmpdec/mpdecimal.c", line: 481)~493
function : mpd_qresize_zero @ (file: "Python-3.3.0a2/Modules/_decimal/libmpdec/mpdecimal.c", line: 501)~517

The two functions perform different in the else if condition. I wonder this is due to functionality requirement or a bug. The source code is included in the attachment. Hope it helps.

You can't return mpd_realloc_dyn(result, nwords, status) in the
second instance: the coefficient must be initialized to zero
later on. So this is intentional.
