Discovered this with OpenOffice.org 2 beta 2 on Windows XP and Debian GNU/Linux.
Enter a value with an alphabetic part and a numeric part such as
"AC711111111111" into a cell, then copy it to the one below. Select both cells
and drag the handle to the cells below. This should copy the same value to the
cells below, but if the numeric part of the value is greater than about 2^31,
data is clipped.

I found that the problem occurs with numeric parts with values 2^31 and over.
Interestingly 2^31 - 1 behaves specially, such that dragging to duplicate the
columns' values causes all but the first cell to be cleared!

The columns do not have a particular format set, however when the format is set
to "Text" (format string of "@"), the problem does not manifest.

I will attach a file demonstrating the problem.
