Re: Apex Legends Crash no error - PC (apex_crash.txt)

@Falkentyne, I honestly don't know how Easy AntiCheat works (I wasn't involved in integrating that), so I can't speak to whether it's a factor.

I do think it's related to the actual instruction sequence, and possibly it's offset in memory. I can try making a standalone test program, that's a good idea. But it's not as trivial as you might think. This function does connect with the rest of our engine, so we have to sever those connections to make a standalone program, but we have to do it in a way that doesn't change the generated assembly.

If that doesn't work, I guess I could write an assembly language file that just has this function exactly as it is in the live game, and try to have external code feed it the data expects in a way that won't crash.

Another tricky thing is that the path through this code depends on branches based on what you can see in the game. If a particular path through the code is causing the bug, you'd need to replicate the live data that causes the crash. That data can be different for every viewpoint in King's Canyon, so even replicating all of the code may not replicate the crash if we don't replicate the control flow decisions. There are things we can try to force different control flows, but it's not guaranteed to repro.

Still, it's worth a shot!
