Access violation crash on pause

[ulex]

Steps to reproduce:
Run DebugViewPP for application with heavy DebugOutputString (1MB per second is enough).

Looks like race condition in LogSources.GetLines.

Last event: 500.1c10: Access violation - code c0000005 (!!! second chance !!!)

DebugView__!fusion::debugviewpp::LogSources::GetLines+0x16e [z:\debugviewpp\debugview++lib\logsources.cpp @ 314] 

	for (auto& inputLine : m_linebuffer.GetLines())
	{
		// let the logsource decide how to create processname
		if (inputLine.pLogSource)
		{
			> inputLine.pLogSource->PreProcess(inputLine);
		}

I was trying to fix this issue, but stuck in threading model. Looks like some synchronization point is required, but I'm not sure where it should be.
