SUMMARY: AddressSanitizer: alloc-dealloc-mismatch (/usr/lib/x86_64-linux-gnu/libasan.so.3+0xc37f0) in operator delete(void*, unsigned long)

Looks like some instances were created with new[], but deleted with just delete (should be delete[]).

For example:
// Allocation
void Generic::setLong( qint32* newValueArray, unsigned long arrayCountIn ) {
deleteValue();
value = new qint32[arrayCountIn]; <---- HERE
if( newValueArray )
{
memcpy( value, newValueArray, sizeof(qint32)*arrayCountIn );
}
arrayCount = arrayCountIn;
type = GENERIC_LONG;
}

// Deallocation
void Generic::deleteValue() {
...
switch( getType() ) {
...
case GENERIC_LONG :
delete (qint32*)value; <---- HERE
break;
...
}
value = NULL;
type = GENERIC_UNKNOWN;
}
