commit dc78e5c6f5f55b0289012f4c4e6013d2935b1cc6
Author: Caolán McNamara <caol...@redhat.com>
Date: Thu Jun 2 11:18:02 2016 +0100
Resolves: tdf#98880 ensure backing context of DoubleVectorRefToken...
exists for the lifetime of the ScGroupTokenConverter
otherwise in tdf#98880 ScDocument::InterpretDirtyCells releases
that backing storage that the DoubleVectorRefToken relies on, and
the ScVectorRefMatrix relies on that, so...
when sc/source/core/tool/interpr4.cxx calls ::IsString on the
ScVectorRefMatrix
which calls ensureFullMatrix. That makes use of rArray.mpStringArray where
rArray's mpStringArray is set to that rArray by
FormulaGroupContext::ensureStrArray and the storage of mpStringArray
belongs to
the FormulaGroupContext, but that context was reset and destroyed up the
stack
in ScDocument::InterpretDirtyCells so the data is now invalid
We could turn the unique_ptr into a shared_ptr and have the
ScGroupTokenConverter
take a ref to the currently active FormulaGroupContext to ensure any
generated
DoubleVectorRefToken/SingleVectorRefToken point to valid data during the
lifetime of the ScGroupTokenConverter
