Error: `free(): double free detected in tcache 2` #59

Closed azazdeaz closed 2 years ago

azazdeaz commented 2 years ago

Hi There, when i try to run the app as described in the readme, it throws:

$ RUST_BACKTRACE=1 cargo run --bin blackjack_ui
    Finished dev [unoptimized + debuginfo] target(s) in 0.13s
     Running `target/debug/blackjack_ui`
free(): double free detected in tcache 2
Aborted (core dumped)

Do you have any tip how should i fix this? This project looks amazing, and i'd love to try it out!

Ubuntu 22.04 rustc 1.64.0 (a55dd71d5 2022-09-19)

Wow, that one's spooky :thinking: Looks like something's triggering UB. There's a tiny bit of unsafe code in blackjack, but there's nothing that would trigger a crash at launch like that. Could be one of its several native dependencies though, I've had issues with rfd and mlua in the past.

Let's try getting a gdb backtrace, sometimes that helps finding the root cause (but not necessarily). Could you try this?

$ gdb -q ./target/debug/blackjack_ui
(gdb) run
# wait for the error to happen ...
(gdb) backtrace
# backtrace should be printed here

Right, it's something with my setup. I tried to compile it on the same machine, but in an Ubuntu22.04 Distrobox and in worked beautifully :tada:

These are the logs. I'd be grateful for any suggestion to fix this, but ultimately it's an issue on my end, so i'll close the issue.

I'm very excited to see the future updates of this project :heart:

setzer22 commented 2 years ago

Looks like the backtrace points to your the Intel Vulkan driver. This does not mean the driver is necessarily at fault, but maybe updating (or downgrading?) the drivers may help?

This looks a bit beyond my reach unfortunately :thinking: Sorry I can't be of more help

azazdeaz commented 2 years ago

If anyone wonders here, the issue happened because i was using the Mesa driver from https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers. Reverting to the official release fixed the issue.
