CBaseEntity_DispatchSpawn signature not found

[oerkmn]

Environment
CounterStrikeSharp: v1.0.367
Metamod: 2.0.0-dev+1396
Platform: Linux (Debian 11 Bullseye)
CS2 PatchVersion: 1.41.5.4
CS2 ServerVersion: 2000797
CS2 SourceRevision: 10607298
CS2 VersionDate: Apr 22, 2026

Description
After the April 21-22 CS2 update, CounterStrikeSharp v1.0.367 crashes with a segmentation fault approximately 14-60 seconds after server start. The crash occurs during map changelevel (de_dust2 → workshop map).
The crash happens with all plugins disabled (empty plugins folder), confirming this is a CSS core issue, not plugin-related.
Error Log
[20:07:23.469] CSSharp: Failed to find signature for 'CBaseEntity_DispatchSpawn'

Followed by:
CSSharp: CGameSystem::Shutdown
double free or corruption (out)
Segmentation fault
Exit code: 139

Additional Context
Tested with three CSS builds (fix/ag2-update branch, v1.0.365 + community patches, v1.0.367 official) — all crash with the same pattern
v1.0.367 only updated CBaseEntity_TakeDamageOld Linux signature but CBaseEntity_DispatchSpawn remains broken
Related: #1283, #1286

Hey is this still happening? Are you on Windows or Linux?

Still hitting it on Linux, can confirm.

Environment matches the original report closely — we hit the same crash testing this matrix back in late April:

CS2	CSS	result
1.41.5.4 (post-AG2)	v1.0.367	segfault inside CBaseEntity_DispatchSpawn ~1s after load
1.41.5.3 (AG2 day 1)	v1.0.367	identical segfault
1.41.4.1 (pre-AG2)	v1.0.367	CSS fails to load with undefined symbol: _Z21ThreadAtomicNotifyOnePKj (version skew the other way)
1.41.4.1 (pre-AG2)	v1.0.365	works

We've been running the last row (CS2 1.41.4.1 legacy beta branch + CSS v1.0.365) as a production workaround for ~6 weeks. Linux Debian-based Docker (ich777/steamcmd:cs2) on unRAID host. Metamod 2.0.0-dev+1396.

Happy to test candidate fixes against our current CS2 build — we have a stable repro environment and the ability to swap CSS versions quickly. Just point us at a branch/commit and we can confirm whether the signature resolves.

Thanks for the information, but I can't replicate in my environment on v368. I have integration tests that run and spawn entities that work without issue.

Are you using a custom GameData file or can you check it matches exactly what's in the repository?
