Summary0005538: Segmentation fault when receiving a new objective in mission "WS3: Cleighmoor"

This is my first bug report, so any comments on how I could improve this post will be appreciated.

Mission: William Steele 3: Cleighmoor (
Save game file: (compressed .tar.gz file)

When loading "Quicksave_0" and waiting a few seconds for the civilian to finish his dialogue with the guard, a new mission objective is supposed to be received, but instead the game exits to desktop with the following output (cropped to immediately after the save game was created):

signal caught: Segmentation fault
si_code 1
Trying to exit gracefully..
--------- Game Map Shutdown ----------
ModelGenerator memory: 23 LOD entries with 3 users using 2713 bytes.
WARNING:idClipModel::FreeTraceModel: tried to free uncached trace model (index=0)
--------- Game Map Shutdown done -----
Shutting down sound hardware
double free or corruption (out)
double fault Aborted, bailing out
shutdown terminal support
About to exit with code 6
Steps To ReproduceLoad the linked save game for the mission "William Steele 3: Cleighmoor" and wait a few seconds and the game should crash.
Additional InformationThis has only been tested on the recently released version 2.09, but I can't select that as an option in the "Product Version" drop-down.

Reproducible with com_smp 0 and com_fixedTic 0 (not affected by multi-core or uncapped FPS)

@nbohr1more: Do I understand you correctly that the crash may be due to my chosen in-game settings (chosen in the main menu), or are these settings that you mention exclusive to the dev console?

@bwyan : Multi-Core and Uncapped FPS are known to be sources of stability issues so I ruled them out.

It is possible that some setting is responsible for this but it seems unlikely now.

As I can tell, the conversation is causing an unhandled clipmodel to be freed.

Probably something that needs to be covered in the Entity destructor...

I will continue to investigate.

@grayman : I don't see a "SewellTalksToSmithson" variable in the script for this mission,
do you know how this conversation is initiated?

When crash happened, gdb showed me frontend thread.
I guess the crash happened inside malloc.
Since size looks OK, this crash most likely means heap corruption somewhere.
It can also explain why it does not lead to crash on Windows.

No idea what to do next. Is it possible to run TDM under valgrind?

When Smithson starts his patrol and walks into "trigger_once_entityname_11", a conversation is started ("SewellTalksToSmithson") between him and Sewell.

I have no clue what's causing the issue. The only known crash in Cleighmoor was fixed years ago by this update:

How easy is it to reproduce this issue without the savegame? It would be very helpful, I think, to know if this already existed in 2.08 or not, so that we could potentially bisect to the problematic change.

I tried to reproduce it on Windows with (full) Debug, but there is no issues like heap corruption detected.
Also tried to run TDM under valgrind, but it produces tons of redirection warnigs, after which crashes deep inside VMWare OpenGL driver during glX initialization.

And yes, I don't see instructions how to reproduce from fresh start. I wonder if it is possible.
