I've put the data form the Junittest on a calc sheet, with the outcomes as I

Presently, I don know whether the Junittest is wrong, or the patch.

Title:
[Upstream] [hardy] Goal Seek hangs Calc
A proper fix will take some time as the problem is deep inside the code,
hidden in a maze of recursive and iterative code.
Also, the chances are that when fixed, calc will no longer hang, but neither
give a solution. The reason for this is that in attachment 46880 the formula in
every cell
I also confirm what Takeshi Abe reported, i.e. that the cause is not in
ScInterpreter::ScBackSolver(), but in SCFormulaCell::Interpret().
At some point the result is no longer calculated but equal to the
previous result, causing an infinite loop in ScBacksolver() since
changing the start value
I have a dirty fix:
The MAXRECURSION (/core/sc/source/core/data/formulacell.cxx) value of 400 is
reached; increasing it 'solves' the problem.
However, there will always be a case where the MAXRECURSION value is reached,
so a proper handling of this situation is required.
Also, a 'best' value
I confirm problem -as described in comment 3 and comment 4 - still
exists on master.
I will look into the code and see if i can find the cause and a fix.

@kohei, @moggi - any input on how to move this ahead? I notice that
easyhack status got lost or removed meanwhile - or can you suggest
Takeshi Abe some more directions to look into?
