Unhandled memcpy_s error in Floor Item Reader causing addon to crash

[funnykeyboardsymbols]

Happens fairly frequently (0-3 times in a TTF, usually 1-2). Have not yet narrowed down what item(s) cause it, but it always happens on item drop. Reloads just fine.

Running through Lutris on Fedora linux. Since this is a C function, I assume some lower level system details might be relevant, but I don't know which ones you would need, and I don't want to just overload you with irrelevant info. I'll keep a close eye on this issue and will be ready to provide any extra info you require.

Update, just happened while Tekking too.

Can confirm that the issue occurs in both 0.3.5.7 and 3.7.0 and still occurring. Saw that 0.3.5.7 had a fix for something involving memcpy_s, so I tried it out hoping there had been a regression in a newer version. No luck.

Also tried several versions of Wine, including Lutris default Wine GE, GE-Proton, and Wine 10.4 staging, none of which made any difference.

I have also tried completely uninstalling the dll and all addons, installing completely fresh, and then playing normally. Issue still occurs.

Would love some info on more things to try, or if perhaps this is an issue you are aware of.

Additionally, since my original issue a week ago, the Monster Reader has also crashed many times. I do not use the Player Reader or Timer. None of the other addons I use crash.

What I find weird is where it is crashing, when reading the weapon group address.

I could suggest adding a log right before the crash, to see what value it has, but the pmt is guarded against being null

                local groupAddress = weaponAddress + 8 * group

                if groupAddress < 0x1000000 then
                    print('Bad group address: ' .. groupAddress)
                end
                
                local count = pso.read_u32(groupAddress)

Here's the output of one crash.

This one is different.

But probably the same issue, reading from a low enough address that throw in memcpy_s.

I will think about this, probably run the game a little bit, maybe give you a new pmt.lua with more logs and/or guards....
I am thinking of just adding guards when this happens so the addon doesn't crash, if it is a temporary issue.

Not sure how much this can be the way you are running the game, maybe ask around if other people running similar setups have the same issue.

Yeah, I have asked around. In fact, I have been playing Ephinea with addons on Linux for years, on and off. In the past, I never had this issue. So I was thinking it was either something with my distribution, my wine version, the updated Ephinea client, or the updated addons. And when asking around, no one else I spoke to had ever even heard of this. So I might just be the first one to run into this issue. I haven't been able to narrow it down to a cause. It seems completely arbitrary.

I would be happy enough with something that simply prevents it from crashing, but a part of me is super curious about the cause, so if you wanna throw me a version that BOTH prevents the crash, AND logs to a file or something, I'd be down to collect a few play sessions' worth of logs and send em your way.

I'll let you know when I throw something together with a new pmt.lua.
