Summary0002994: Crashes when a new player connects to server (only when all players disconnected previously).
DescriptionServer constantly crashing with fatal error:
*** Fatal Error ***
Address not mapped to object (signal 11)
Address: 0x370
Steps To Reproduce1. Join irc.zandronum.com #tspg-painkiller.
2. Create an account and identify yourself.
3. Login to tspg website, your account, slots, and save this into slot 1:
.host iwad="doom2.wad" hostname="$$$ MY TEST SERVER $$$" wad="hpbar-v15b.pk3,chillax-v9.7.3.wad,ro_pb_2.2_zan_01.pk3,ro-ark-1g.pk3,arkcore-1g4.pk3,arkcore-ro-1g.pk3" config=arkcorechillaxro.cfg gamemode=survival skill=1
4. In irc #tspg-painkiller window, type .load 1
5. Join server. Enter game.
6. Use rcon to changemap to any other map. (this step might be optional).
7. Now leave the server.
8. Ensure that everyone has left the server.
9. Now have someone else join the server. Crash.
Additional InformationI tried to re-produce this locally, but I cannot. I think I cannot re-produce because the game remembered me some how.

Did you check with the zandronum server tspg version?

The crash logs show that there's an ACS script which calls 'strlen' with an invalid argument.

If'https://bitbucket.org/Torr_Samaho/zandronum-zdoom-sync/commits/62e4cfc78a7f20d68cf59f4e6c5a733311fe6d3a [^]' is backported, the problem should be gone.

Thanks, I'll get around to testing this.

I managed to fix it on my end too. There were several problems causing crashes or maybe it was only one problem. E.g. Significant SetActivator() usage from an OPEN script(which wiki recommends against doing), while having other scripts running and also using SetActivator(), while having Delay() usage.

It all came down to the fact that I wasn't clearing the player's TID after they died (because I was trying something new this time, and I thought it would work).

This resulted in multiple players(your corpses) having the same TID, and so when you try to use UseActorInventory() it crashes.

Or if a player died, and remained dead, and a new player connects to the server and server immediately crashes.

Anyways.

I've taken what I learned (about TID assignment and re-assignment on DEATH(or RESPAWN)) and finally updated the zdoom wiki(https://zdoom.org/wiki/Thing_ChangeTID), adding an example snippet of code of using RESPAWN(instead of DEATH) to clear the player's TID, and adding a note about how it's very important that the player's TID be cleared on DEATH(or RESPAWN).

Thanks,
