[lto]

I was able to fix the problem I described in private message.
I am on Windows I was able to attach debugger and reproduced crash multiple times in same place:

	...
	              if (server->f_cur && server->rc.m_mediaChannel && !paused)
	                {
>	                  server->rc.m_pauseStamp = server->rc.m_channelTimestamp[server->rc.m_mediaChannel];
	                  if (RTMP_ToggleStream(&server->rc))

{

I checked if server is 0 but it didn't help, so I just called inside this if:

goto cleanup;

and it works, no more crashes with rtmpdumphelper

I think in some cases this server structure is messed up and crash happens
