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?
