Hi Watson, Thanks for taking a look! This is where it crashes in TwUI: https://github.com/twitter/twui/blob/master/lib/UIKit/TUIView.m#L311 Cheers, Isaac On Sat, Dec 24, 2011 at 11:59 AM, Watson <watson1978@gmail.com> wrote:
Hi,
Now I have seen your project. Apparently, it is crashed by lib/views/ExampleTabBar.rb(line:10)
To determine the cause, I need more time.
Thanks,

I should have also mentioned that I can reproduce this crash on MacRuby 0.10, 0.11 and the latest nightly build.

TwUI is a hardware accelerated UI framework for Mac, inspired by UIKit: https://github.com/twitter/twui
I'd like to try using it in my MacRuby apps, so I thought to start with I would port the the TwUI Example Project to MacRuby.
TwUI Example Project: https://github.com/twitter/twui/tree/master/ExampleProject MacRuby: https://github.com/isaac/TwUIExample
I got a basic version of the example app working, but as I was implementing the tab bar the app crashed with this exception:
Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x000000000000000a
Here is the full crash report: https://gist.github.com/78e7f9870b788e8fd4c9
I have tried to make this crash easy to replicate by writing a Rake task and instructions for installing the TwUI framework for MacRuby - details here: https://github.com/isaac/TwUIExample/blob/master/README.md
The app was originally written with HotCocoa, but there is also an Xcode version that reproduces the same crash here: https://github.com/isaac/TwUIExample/tree/master/Xcode
I thought this might be related to the fact that TwUI doesn't use garbage collection, but I can also reproduce this crash with a fork that uses ARC here: https://github.com/jspahrsummers/twui/tree/SnowLeopardCompatibility
Let me know if I should open a Trac ticket about this, I'm not sure if it is a MacRuby issue or not.
Any help would be greatly appreciated!
Cheers, Isaac
