Description sauvard 2010-04-07 21:36:40 UTC
In the supplied tst.xml document there are circular references.
The iteration stop before convergence.
It seems that a new value of a cell is not propagated completely until returning
to the cell but stops before.

There is a small chance that this is related to issue 956 but here the calculus
is non linear.

Cell E1 of attachment in 2.4.3 when opening file shows 3498.48 = converged answer.

Cell E1 of attachment in Rev. 1503704 when opening file shows 332.7626332864. It takes 17 times(!) Ctrl-Shift-F9 to reach 3498.4763682112.

Why the 'regression' keyword?
Why importance 'major'?

This is why regression.
Comment 5 Edwin Sharp 2014-02-18 13:32:30 UTC  :
"major: The bug cause function doesn't work but there is typically workaround. It includes but is not limited to:

    Basic function doesn't work correctly
    Data lost
    Crash in special circumstances
    Examples: Cannot rename a sheet, document saved without character font setting"

This is why major.
