QMultiHash - crashing

[steg90]

Hi,

I have the following code :

QList<QObject*>Signals;
 
	if( theApp->m_dcb.m_oSignalMap.count() > 0 )
	{
		Signals = theApp->m_dcb.m_oSignalMap.values( strId ) ;
		if( Signals.size() > 0 )
		{
			CDADcb::CSignal* pSignal = (CDADcb::CSignal*)Signals.at(0);
 
			// This signal belong to this CAN id, there can be many signals that do
			{
				// we need to do the conversion here - TODO
				pSignal->m_strRawData = strData;  
				pSignal->m_nCount++;
			}
		}
	}

QList<QObject*>Signals;

	if( theApp->m_dcb.m_oSignalMap.count() > 0 )
	{
		Signals = theApp->m_dcb.m_oSignalMap.values( strId ) ;
		if( Signals.size() > 0 )
		{
			CDADcb::CSignal* pSignal = (CDADcb::CSignal*)Signals.at(0);

			// This signal belong to this CAN id, there can be many signals that do
			{
				// we need to do the conversion here - TODO
				pSignal->m_strRawData = strData;  
				pSignal->m_nCount++;
			}
		}
	}

To copy to clipboard, switch view to plain text mode 

m_oSignalMap is a QMultiHash<QString, QObject*> of which CSignal objects are stored keyed on a string value. For some reason, this bit of code causes my application to crash at incoherent intervals, sometimes after a minute, sometimes after 5. The crash is in QHash.h when trying to find the key ( the key seems to be a bad ptr? ).

Sorry I can explain more, just seems so hit and miss...
