consistency check showing lots of NEW errors after saving file with new version

[Jack]

I just compiled a fresh version, and the first time I saved, the  
consistency check came up with over 4000 problems.  ALL are in  
investment accounts, several of which have been closed for many years.   
I suspect it's an unintended side effect of the recent work on storing  
prices for add/remove share transactions.

Just the first example:
   * Sum of splits in transaction 'T000000000000000004' posted on  
4/16/2001 is not zero.
     Account: Asset:ML Overall:ML Stock (Brokerage), Amount: $-8,005.00
     Account: Asset:ML Overall:ML   55741 CMA:Pfizer Common, Amount:  
PFE1,402.0000

That was the initial Buy shares transaction in that account, and as the  
fourth transaction in my file, it was clearly LONG ago.

Extracting the transaction gives:
<TRANSACTION id="T000000000000000004" postdate="2001-04-16" memo=""  
entrydate="2009-08-24" commodity="USD">
     <SPLITS>
         <SPLIT id="S0001" payee="" reconciledate="2009-12-31"  
action="" reconcileflag="2" value="-8005/1"
                shares="-8005/1" price="1/1" memo="Grant 08251994 0428"  
account="A000133" number="" bankid=""/>
         <SPLIT id="S0002" payee="" reconciledate="" action="Buy"  
reconcileflag="2" value="400271/50"
                shares="1402/1" price="571/100" memo="Grant 08251994  
0428" account="A000153" number="" bankid=""/>
     </SPLITS>
</TRANSACTION>

but extracting it from a backup from before I first save it today gives:
<TRANSACTION id="T000000000000000004" postdate="2001-04-16" memo=""  
entrydate="2009-08-24" commodity="USD">
     <SPLITS>
         <SPLIT id="S0001" payee="" reconciledate="2009-12-31"  
action="" reconcileflag="2" value="-400271/50"
                shares="-400271/50" price="1/1" memo="Grant 08251994  
0428" account="A000133" number="" bankid=""/>
         <SPLIT id="S0002" payee="" reconciledate="" action="Buy"  
reconcileflag="2" value="400271/50"
                shares="1402/1" price="571/100" memo="Grant 08251994  
0428" account="A000153" number="" bankid=""/>
     </SPLITS>
</TRANSACTION>

Split 2 (in the security account) is the same before and after, but  
split 1 (in the brokerage account) has had the value and shares  
converted from 8005.42 (400271/50) converted 8005 (8005/1.)  It looks  
like the new save has a rounding problem of some sort, or possibly a  
truncation in writing the number.
