Server Crash on "quit"

[MAGNAT2645]

This extensions crashes my Linux server (local on Arch) when i run quit (via LinuxGSM's tf2server stop) to stop the server.
There are no any errors or dumps when this happens. Accelerator doesn't seem to notice this kind of crash because it happens on SDK unload, after these lines:

SDK unload
metamod SDK unload

Then all i see in logs is the message about server restarting in 10 seconds.

And server crashes even if i don't use extension features in any plugin, the extension just need to be loaded to crash.
But it doesn't crash if i unload it via sm exts unload though.
