Hello,
When I run IOC of AMC100, I found this issue.

Connect to virtual motor controller server

drvAsynIPPortConfigure("AMC-1_IP","192.168.0.110:9090", 0, 0, 0)
#ScriptControllerConfig( "PORT_NAME", num_axes, "lua_script", "PARAMS=")
ScriptControllerConfig("AMC-1", 2, "Attocube_AMC.lua", "PORT='AMC-1_IP'")
xxx: ../../../luaApp/src/luaaa/luaaa.hpp:979: luaaa::LuaClass< >::LuaClass(lua_State*, const char*, const luaL_Reg*) [with TCLASS = _apdWrapper; lua_State = lua_State; luaL_Reg = luaL_Reg]: Assertion `klassName == nullptr' failed.
Aborted (core dumped)

I've tracked this down to a problem with the CPP class binding code and not being able to have it linked to multiple instances of lua environment at the same time (each axis gets its own environment).

I've opened up an issue with the luaaa library maintainer. In the meantime, you can deactivate that functionality and go back to the simpler libraries by putting CXX11_SUPPORT=NO into CONFIG_SITE.local.Linux and rebuilding.

I believe that I've made a temporary fix with 8ad0ee0 , though an upstream fix to the library would need to be more complete.
