Alasdair: thank you for this report. We had that trouble for a while,
but it should be fixed in current builds (i.e. any after 2003-02-17).
It had to do with floating point errors on Windows for large integers.

Verified Duplicate. 

Please reopen this bug if current trunk builds (rv:1.4a) 
still show the problem; thanks!
