Git commit a583dc9d434ec1f42bc417769adcf3449dea741c by Ralf Habacker. Committed on 31/08/2017 at 17:47. Pushed by habacker into branch '4.8'. Fix 'Crash on investment charts with multiple investments' The root cause of this crash is an implementation bug in CartesianDiagramDataCompressor::slotColumnsAboutToBeInserted(). In case m_model is set, adding columns to m_data requires to add a QVector<DataPoint> instance sized to the model row count. Instead the size is limited to m_xResolution which depends on the diagram zoom factor and other values. Having a too small sized column in m_data let slotRowsAboutToBeInserted() crash. This patch needs to be pushed upstream to have it in further kdiagram releases. Fixup of commit 7516308b. FIXED-IN:4.8.1 M +1 -1 libkdchart/src/KDChart/Cartesian/KDChartCartesianDiagramDataCompressor_p.cpp https://commits.kde.org/kmymoney/a583dc9d434ec1f42bc417769adcf3449dea741c
Fix has been added to kmymoneys 4.8 kdiagram source copy for now.
Afaics this fix is included in KChart 2.6 so closing it.
