For HLDM without Metamod yes - With Metamod no. I don't know why it crashes and the GDB gave me a huge list of errors linked to metamod.so - even without the other Addons like AMXX and Spawn & Chat Protection.
Code:
Program received signal SIGBUS, Bus error.

I don't know much on how you code for Sandbot, but is it possible that those bots only work if the builds were split to do only load as a Standalone and as a Metamod build? E.g sandbot.dll and sandbot.so for Standalone and sandbot_mm.dll and sandbot_mm.so for Metamod?
