Xcode 5 keeps crashing while editing .eero / .eeh file

[waynezhang]

Both Xcode 5 and 5.1DP on my Macbook Pro keep crashing while editing eero files. Even when I did not change anything but only moved cursor.

Here is the log:

Looks like version of 13-Nov-2013 works fine.
But auto completion seems not work in Nov version.

[andyarvanitis]

Thanks for the report. Looking at the logs, I can't really see anything related to the plugin, so I'm not sure what went wrong. Now that it's working for you with the Nov build, would you mind trying the Dec build again and let me know if you still see problems? Thanks!

[waynezhang]

@andyarvanitis Dec build still causes crash. I also tried to rebuild the plugin from scratch but problem still remains.

[andyarvanitis]

Ok, thanks again. I'll see if I can find a way to reproduce it here. I'm also running 10.9.1 and Xcode 5.0.2.

[andyarvanitis]

Fixed in ad40f63

[waynezhang]

Technically ad40f63 is a fix for another problem, but after using sublime text for a few days, Xcode does not crash these days when I tried again. Don't know why.

[andyarvanitis]

Ah ok, I'll reopen it. That is strange.

[andyarvanitis]

New binary (updated installer) coming soon.

[andyarvanitis]

I haven't been able to reproduce it, but I have posted a new installer: http://downloads.eerolanguage.org/easy%20installer/Eero%20Support%20for%20Xcode%202014-03-08.dmg. It includes the pull request and compiler binaries based on the llvm/clang 3.4 stable release. Tested with 5.0.2 and 5.1-beta5. When you get a chance, can you try it out?

[andrebraga]

Sorry to say but on Xcode 5.1 GM this is still broken. 💔

[andyarvanitis]

Thanks for the report. I've been very tied-up lately with day-job deadlines, but I'll do some testing with 5.1 asap, this weekend at the latest.
