Start failure on IDA Python 3.12

[MinatoTW]

After installing via pip and selecting IDA pro, IDA pro crashes with "Error 1442" on opening. Problem is resolved after deleting decomp2dbg file and folder from plugins.

Python version 3.12 on Arch Linux 64 bit.

And you're 100% d2d is the only culprit? I ran latest d2d on ida 8.4 for Mac and it worked great this weekend.

I find it strange since the plugin, on load from ida, only makes a toolbar menu.

[MinatoTW]

Yes, I'm sure. It happened as soon as I installed the plugin and goes away when I delete it. Looked at the strings in the generated IDA dump and it had the d2d file path in it.

Alright, this one may take a while to close. I don't have access to a Linux copy of IDA Pro 8.4 yet, and I don't see any obvious bugs in our current implementation. Maybe 3.12 is a culprit here. Any chance you can execute your idapyswitch binary in your IDA install, switch to non-3.12, and report back if it still does this?

[MinatoTW]

Yup, it was 3.12, works with 3.10. Thank you, this plugin is amazing.

Although, now after i connect with GDB (GEF) I get the error [!] Command 'context' failed to execute properly, reason: 'NoneType' object has no attribute 'items'.
It's able to resolve main but no pseudocode. I guess that's related to the python version too?

[MinatoTW]

Never mind, that binary had issues with decompilation due to a huge stack frame.

I can confirm that I also had the same issue. The binary was normal, IDA segfaults when run with python version 3.12:

Oops, IDA has almost crashed! (signum=11)
fish: Job 1, 'ida ./babystack' terminated by signal SIGSEGV (Address boundary error)

but works with 3.10.

@k4lizen, would you be able to attach the binary for testing?

[k4lizen]

yeah you can get it here: https://pwnable.tw/static/chall/babystack
