Expected Results:
no assert
Reproducible: Always
User Profile Reset: No
Additional Info:
load document ~/Downloads/forum-mso-en4-784502.xlsx
after it has loaded:
(gdb) break column4.cxx:1946
(gdb) break column4.cxx:1966
data, recalculate, recalculate hard,
the first time breakpoint #1 gets hit:
at column4.cxx:1946 NeedsInterpret is true, so cell
{nRow = 1, nCol = 0, nTab = 3 } was dirty and is set
not-dirty by Interpret. mxGroup->mbPartOfCycle is false
so this returns successfully to allow threading.
the bt to there was:
#0 lcl_EvalDirty(mdds::mtv::soa::multi_type_vector<sc::CellStoreTraits>&, int,
int, ScDocument&, boost::intrusive_ptr<ScFormulaCellGroup> const&, bool, bool,
bool&, bool&)
(rCells=..., nRow1=1, nRow2=4, rDoc=..., mxGroup=...,

#5 0x00007fff9f30085a in

#6 0x00007fff9f2ff392 in

bDependencyCheckFailed=@0x7fffffff56d6: false, nStartOffset=0, nEndOffset=3)
at sc/source/core/data/formulacell.cxx:4829
so the CheckComputeDependencies at the start of
ScFormulaCell::InterpretFormulaGroupThreading
is successful for aPos of {nRow = 1, nCol = 1, nTab = 3 }
and the cell is not dirty at that point
*however* in the following loop of
for (SCCOL nCurrCol = nColStart; nCurrCol <= nColEnd; ++nCurrCol)
in InterpretFormulaGroupThreading, CheckComputeDependencies for
column 3 is called and the breakpoint #2 is hit, in this case
mxGroup->mbPartOfCycle is true and the {nRow = 1, nCol = 0, nTab = 3 }
cell is set dirty again.
so later during the threaded calculation the cell is found dirty and
the ScFormulaCell::MaybeInterpret() assert that
!rDocument.IsThreadedGroupCalcInProgress()
first :-(
