Interesting the _ReadWriteBarrier() intrinsic does not work even though that is what it is designed for. I manually add a memory fence using a locking intrinsic or just disable optimisation of the entire function. For high performance of TCP it is probably better to go with adding the intrinsic.
To reproduce just run the following a few times and see if it locks, remote_thr.exe "epgm://10.6.28.35;239.192.0.1:7500" 10 10 Patches are not signed because there are two options, therefore I explicitly state these patches are released under the MIT/X11 license. -- Steve-o
