[QGIS-Developer] WG: Re: crash qgis 2.18.11 in vs2010 - HEAP CORRUPTION DETECTED

[SSchmidt at gfi-gis.de]

If I compile my plugin with Option Runtime Library:
Multi-threaded Debug DLL (/MDd)
at first sight it works fine, but while closing QGIS, QGIS crashes with 
'HEAP CORRUPTION DETECTED'


Then if my plugin is 
Compiled with Option Runtime Library:
Multi-threaded DLL (/MD)


I get the error:

>       msvcr100.dll!free(void * pBlock)  Line 51       C

during deleting the symollayer from this code:

QgsSymbolV2 * p_Symbol(0);
bool oFirst=true;

...

if (oFirst)
{
        QgsFillSymbolV2* p_FSymbol = new 
QgsFillSymbolV2();//QgsSymbolLayerV2List()
        p_Symbol = dynamic_cast <QgsSymbolV2 *>(p_FSymbol);
        qDebug()<<QString::number((int)p_Symbol,16);
        qDebug()<<QString::number(p_Symbol->symbolLayerCount());
        if (p_Symbol->symbolLayerCount()==1)
                p_Symbol->deleteSymbolLayer(0);
        oFirst=false;
}
...

Output:

"1847bca0" 
"1" 
First-chance exception at 0x77e4e43e in qgis-bin.exe: 0xC0000005: Access 
violation reading location 0x4d46be13.
Unhandled exception at 0x77e4e43e in qgis-bin.exe: 0xC0000005: Access 
violation reading location 0x4d46be13.


Could this correspond with the message: "QgsFillSymbol::scalar deleting 
destructor"?
It's horrible for me with the pointers :-o
I create the FillSymbol with "new" in my DLL but something's going wrong 
by deleting.
Any hope for me?

Are you using the GEOS C++ API directly or is this from calling QGIS 
methods?
