Crash Offsets

Hello it’s me again!

Never got to the bottom of the odd jflp offset, but it doesn’t seem to happen on the server or anyone else’s machine so it’s not a big worry for the moment. However, we’ve got another rather odd problem:

When players on the server enter (almost any) pirate bar, the server crashes with a fault in content.dll with no console output:

Faulting application name: FLServer.exe, version: 1.35.1254.11, time stamp: 0x3ecbb13e 
Faulting module name: Content.dll, version: 1.0.1254.11, time stamp: 0x3ecbb142

Report Id: ef1eba63-3da5-41f7-b5ad-2784fb0efded

Any ideas? It’s definitely not diff2money.ini, loadouts.ini or mbases.ini causing the problem as far as we can tell, and we’ve otherwise not changed anything in relation to factions, bars or bases at all.

Edit: The same bars crash to desktop in SP as well, with no spew output.

I think it might be commodities for jobs.

I can’t test this for a couple of hours, but we have an entry for:

[Commodity]
nickname = commodity_bounty_voucher
ids_name = 524505
ids_info = 524506
units_per_container = 1
pod_appearance = cargopod_blue
loot_appearance = lootcrate_blue
decay_per_second = 0
volume = 0
hit_pts = 250

in st_equip.ini and a goods.ini entry for it. They’re in NPC cargoholds right now (and don’t seem to drop, but perhaps that’s another issue)

Could this be doing it?

The good and equipment nicknames must be the same, so provided the good is also [c]commodity_bounty_voucher[/c] it looks okay.

Removing reference to the new commodity doesn’t seem to fix the crash. When you say commodities for jobs, do you mean the stuff that npcs drop as mission objectives to capture/destroy or something else?

Mission objective (it seems to point to a commodity nickname, so that’s what I’m assuming).

So I’ve isolated this to rmlootprops.ini. We removed some entries (as various guns are not being used anymore and we don’t want them to drop)

I’m not entirely sure what’s causing it to crash, but it seems if certain things are made unavailable (notably if I change the faction to a placeholder one) the bar crashes the game/server. I guess I’ll adjust drop rates using the lootable flag rather than using this file.

Triggered by warping to a base that doesn’t have a physical presence, but has an mbase and universe entry, I think.I was warping to st03b_01_base for testing.

One to add from Laz’s crash hopper:

0E99458F ((module-name not available)): (filename not available): IDLL::operator=

Found a pretty weird one

I’ve done my best to collate the offsets in this thread into a wiki page. Still a bit of a mess, and I’ve probably missed a few. Please feel free to add/adjust stuff as you all see fit! Figured it’d be a bit easier to search through this page than the entire thread.

Looks good. Maybe omitting the 0x prefix as in the Limit Breaking 101 wiki looks nicer?

I’ll have a look at it! There’s a few offsets here that I haven’t put in as I’m not really familiar with converting from relative to absolute/etc and not want to completely muck things up. If anyone who’s a bit more knowledgeable feels like adding stuff I missed that’d be really great.

I like the 0x part for copying to my code purposes. Time saver.

0x00012e10 in content.dll
0x062FFBEB in common.dll

Relates to a bad NPC costume (inconsistent gender choices according to IDA) in mBases.ini. Many thanks to Laz for helping pin this one down.

0x0004fe6c in common.dll

CShip::Launch causes a CTD when the client and server don’t have matching base nicknames in the [Object] entry in a system INI. The client is the one that has the CTD.

Example:
Reproducible by running a vanilla v1.1 server and a JFLP v1.25 client and undocking from either Ronnenburg Base or Yanagi Depot. Client crashes immediately at undocking cutscene. If the inverse is performed, the same outcome is achieved.

Reason:
Vanilla entry for Ronnenburg is nickname = Bw02_02_Base, JFLP v1.25 entry is nickname = Bw02_02
Vanilla entry for Yanagi Depot is nickname = Bw05_03_Base, JFLP v1.25 entry is nickname = Bw05_03

Why:
FL multiplayer black magic?

Just thought I’d drop in and mention that the crash offset database is now available as a json payload through the new TSP wiki!

If you have any automation or scripts that handle Freelancer when it crashes, you can call on this file to try and correlate the offset with your Windows Event logs. A working example of how you might go about doing this can be found here.

Got a new crash for a new forum! I’ve not been able to pin this one down at all:

Not been able to replicate this one reliably, which is a bit frustrating, and I’m not really sure where to start investigating as it’s a system DLL. Any ideas? Suspect it’s related to NPCs in some way, given what I was doing when this occurred.

Could you run it in a debugger (OllyDbg, x64dbg, WinDbg)? That would enable you get a call trace and (hopefully) find where in Freelancer it called the system.

Unfortunately I’ve been unable to reliably replicate this one and haven’t been able to get the game to crash in the same area again! I’ve made a note so it should flag up the next time it occurs while I’m testing. If I can reliably get it crashing I’ll try running it with my client hooks w/ the debugger attached, and if that fails, with OllyDbg
