You'll also want to change the param types from "cbaseentity" to "int" so DHooks doesn't convert them to entity indexes, which is also why you're getting crashes.

Thanks for your information, but nonetheless it's still crashing on Windows in my attempts.

Current setup (works on Linux L4D1):

"Games"
{
    "left4dead"
    {
        "Functions"
        {
            "PassEntityFilter"
            {
                "signature"			"PassEntityFilter"
                "callconv"			"cdecl"
                "return"			"bool"
                "this"				"ignore"
                "arguments"
                {
                    "a1"
                    {
                        "type"		"int"
                    }
                    "a2"
                    {
                        "type"		"int"
                    }
                }
            }
        }
        "Signatures"
        {
            "PassEntityFilter"
            {
                "library"		"server"
                "linux"			"@_Z22PassServerEntityFilterPK13IHandleEntityS1_"
                "windows"		"\x2A\x2A\x2A\x2A\x2A\x2A\x2A\x75\x2A\xB0\x2A\x5F\xC3\x56"
				/* ? ? ? ? ? ? ? 75 ? B0 ? 5F C3 56 */
            }
	}
    }
}

Tried a few possible setups before I gave up on this, which includes adding an argument whilist setting "a1" to be passed in "ebx".
Given it's always a crash regardless of what's in the detour callback (empty callback included), I started to dig out a few hints from crash logs, until I met with multiple ones labelled unique signature crash.

Plugin setup:

PHP Code:

public void OnPluginStart()
{
    Handle hData = LoadGameConfigFile("CollisionHook");
    
    Handle hDetour = DHookCreateFromConf(hData, "PassEntityFilter");
    if (!hDetour) 
        SetFailState("Failed to find \"PassEntityFilter\" offset.");
        
    if (!DHookEnableDetour(hDetour, false, PassEntityFilter)) // tried both pre and post hook
        SetFailState("Failed to detour \"PassEntityFilter\".");

    delete hData;
}

public MRESReturn PassEntityFilter(Handle hReturn, Handle hParams)
{
    return MRES_Ignored;
} 


Several crash IDs:

XCOI-K4MM-OETP
YKWD-K76T-OXYS
A2Y6-CIZK-VEW4
