srcds crash with Assertion Failed: Narrowing inPtr to toClass returned NULL

[CherryJim]

Happening on my dedicated server. Sometimes it takes hours, and other times this happens 5 minutes after boot. I've yet to come up with a way to reproduce it though.
Windows 2k3.

The console command "test_workshop" will crash any server if ran from the client, this is the error produced.

Wow. Thanks for the quick response anyway.

Temporary fix that will stop most attempts. Use at personal risk, may cause clients to unexpectedly disconnect when right clicking (with console open).

I tested "test_workshop" and indeed it will crash any server. Needs immediate fix.

Wrote a quick binary to remove it since concommand.Remove/Add didn't work.

Windows version: [url]http://puu.sh/1jSSa[/url]

Save as gmsv_test_workshop_fix_win32.dll in garrysmod/lua/bin, require it serverside to remove it.

Source:

#define GMMODULE
#include "GarrysMod/Lua/Interface.h"

#include "tier1/tier1.h"
#include "tier1/interface.h"
#include "vstdlib/cvar.h"

GMOD_MODULE_OPEN()
{
	CreateInterfaceFn tier1Factory = VStdLib_GetICVarFactory();
	g_pCVar = (ICvar *)tier1Factory( CVAR_INTERFACE_VERSION, NULL );
	g_pCVar->UnregisterConCommand( g_pCVar->FindCommandBase( "test_workshop" ) );
	return 0;
}

Linux coming soon

Thanks a bunch Drake. <3

EDIT: Getting "Couldn't load module library" with simply require("test_workshop_fix")
Win2k3

[Drakehawke]

Yeah someone else reported the same, odd, fine for me

You don't need a module to stop this..

alias test_workshop ""

[lorde banana]

yeah too bad it doesn't work

[BlackAwps]

[lua]require( "cvar3" )

local test_workshop = cvars.GetCommand( "test_workshop" )
if test_workshop then
test_workshop:SetFlags( FCVAR_DEVELOPMENTONLY )
end[/lua]

With cvar3 loaded, the cvars library seems to be fucked up. cvars.Bool, as well as cvars.AddChangeCallback no longer exist.

alias needs to be run on the client side for it to be effective, however alias is banned from being accessed so we have no way of lua_run or using RunConsoleCommand to set an alias on the client side.

Your DLL works, but for some reason when I have it loaded it causes the server to crash on changelevel.

The alias works serverside too, I tried it out.

Try redownloading it (I updated the link above), I missed something out in the first version that I think might be causing the changelevel crash.

I never bothered with the Linux version since alias test_workshop "" was found, but garry posted his own fix in this thread: [url]http://www.facepunch.com/showthread.php?t=1221645[/url]
