[TF2] Windows crash on client connect

[laurirasanen]

srcds on windows is crashing immediately after client connect with message Unable to find return address. You are going to crash now!. First seen in sp commit 08635a3. Earlier versions seem to work fine.

sp info?

Seems like some offsets recently changed for that game which caused this issue. They should be up-to-date into 8e6f820. If you have auto_data_update enabled into your ../cfg/source-python/core_settings.ini file they should be pulled automatically when you restart your servers.

Thanks for the report!

Still crashing with auto_data_update enabled. Here's the sp info:

Here's the console output:

There is one more fileio assert after these ones but it's hard to catch since the srcds window closes itself and doesn't seem to get logged anywhere.

It did fix it for me. With auto_data_update disabled and v705:

Can you please make sure the 3 modified files into 8e6f820 are properly being updated?

[laurirasanen]

For some reason I had the latest data zip file which stops auto_data_update from applying but the .ini files were out of date. Applying the files from 8e6f820 manually or just deleting the data.zip and restarting has fixed the issue. Thanks!
