Binary Ninja keeps crashing, nothing in logs, how to get more info about what is hapenning?

[bukowa]

I have problems when analysis binaries.
Near the end of analysis all of a sudden binary ninja can just dissapear from process list.
I have no idea what is going on, it's latest stable and Win 11.

With debug loggin to file still nothing, last line:
[6367494314160963727:12341949104546313511 Function debug] 0x101469214: Function analysis took 0.129 seconds

I wonder how can I gather more info about what is really hapenning?
It just exists silently.

Can you share the binary?

vivid beam echoes ultimately

[plafosse]

thanks what edition of binary ninja are you using and which OS?

[bukowa]

Win 10 on 5.3.9434-Stable

So analysis completed just now on my box

have you changed the maxFunctionSize analysis.limits.maxFunctionSize setting? Additionally this took ~17GB of RAM on my machine so I'd make sure you're running it on a machine with enough RAM. Additionally try to run without plugins enabled if you do have plugins installed.

[bukowa]

Hey, my settings:

analysis.limits.maxFunctionSize: 65536
I have 64GB ram
I have free version so no plugins for me

1. If this is related to RAM then why I am not notified about anything / why is binary ninja crashing without any information?
2. Are you running full analysis in 155 seconds?

[plafosse]

It looks like we may have been able to track down the bug you've been running into and it looks like a bad assumption in our Rust API. #8155 We have a PR that has been approved. However since you're on Free I don't have an exact timeline on when this will be fixed in the free edition. We plan update the free client in about 2 weeks. Paid customers will have access to the fix in a couple of hours when the next build is released. Sorry I don't have a better immediate answer for you.

Thank you very much, that is great to hear. I just tried on the same version using WSL on Windows and it works just fine. Also the Linux version completed analysis much faster.
