I have tested your new binary with the latest release of HLDS (48/1.1.2.7 6027). On AMXX 1.8.2, it works but another bug has occured. After you die, you respawn, and after 3 seconds, you are being respawned again, but with freezetime. Here you have a demo:

I thought it was a round bug, bug I have tested it with your Infinite Round plugin (2.1.2 + Orpheu 2.5.1 + Cvar Utilities 1.6) and it is still there.
On AMXX 1.8.3-dev-hg83 it still crashes the server when choosing the team. It gives some error messages in console after I press Close on the crash warning given by the OS, but they aren't logged. I don't know how to store them.
All the tests were made with FFA off.
