[reSIProcate] Strange heap corruption message

[Matthias Moetje - TERASENS GmbH]

Just in case anyone is interested, I found the solution now.
Reason was that I mixed runtime libraries (debug and non-debug)
because some components were compiled for debug and
some for release. 
The strdup function in ares is uses to fill the channel->lookups
parameter while 'free' is used to destroy it. One of these
functions was used from the debug library (strdup is using 
malloc internally) and the other one from the non-debug
runtime library, thus it was created on one heap and
freed on a different heap (each runtime library uses its
own heap). This had caused the heap corruption error...
 
Best regards,

	Hi,
	 
	I am experiencing some strange heap corruption message cause be the following line executed from the destructor of ares:
	free(channel->lookups);

	(ErrorMsg is: HEAP[svchost.exe]: Invalid Address specified to RtlValidateHeap( e80000, e92bf8 ))
	 
	I am not sure if this is the true reason for the error, maybe if has rather to do something how I create and destroy the stack.
	 
	Creation:
	 
	 mStack = new resip::SipStack();
	 mDum = new resip::DialogUsageManager(*mStack);
	 mStackThread = new resip::StackThread(*mStack);
	 mDumThread = new resip::DumThread(*mDum); 
	 
	Destruction:
	 
	  if (mStackThread) 
	  {
	   mStackThread->shutdown();
	  }
	

	  if (mDumThread) 
	  {
	   mDumThread->shutdown();
	  }

	  if (mStackThread) 
	  {
	   mStackThread->join();
	   delete mStackThread;
	   mStackThread = NULL;
	  }

	  if (mDumThread) 
	  {
	   mDumThread->join();
	   delete mDumThread;
	   mDumThread = NULL;
	  }

	  if (mDum) 
	  {
	   delete mDum;
	   mDum = NULL;
	  }
	 
	  if (mStack) 
	  {
	   delete mStack;
	   mStack = NULL;
	  }
	
	Do you see any problems with this code or should I look elswhere for the problem with the heap corruption..?
	 
	Thanks and best regards,

	Matthias Moetje
