Description:
Mysql-workbench just crashes after I made some changes to EER diagram and called unsuccessful forward-engineer
The app prints a lot of stacktraces on crash to stdout.

How to repeat:
Scenario:
1. I start the app
2. I double-click my EER Model under "Open Existing model" at home tab, it opens Model tab and EER Diagram tab
3. I edit the diagram, couldn't localize which exact action causes the issue. Something with editing table columns... But the issue will be unleashed later.
4. I press Ctrl+G to forward-engineer. Clicking next-next and see the empty generated "Review SQL Script". This means the issue is here.
5. I try to close EER diagram tab to "refresh his brans", but it crashes instead.

console out for app crash

I first met the issue on 5.2.33, upgraded today to 5.2.34, but the issue persists.

I couldn't repeat on Ubuntu 11.04 (VisrtualBox).

I also cannot repeat it easily, there's some key action or series of actions that must be made to reproduce it. I will try to locate it and report.

Any guestures on stack traces?

Ok, I found shorter sequence:
3a) I double-click any table, add any column, press Ctrl+S, Ctrl+G and go with forward-engineer successfully.
3b) I repeat step 3a with other table and issue reproduces

Hello Andrey,

I just can't reproduce your bug, is it happening with all the Models you work on? or is it an specific model?, will be great if you can share with us the EER model (as a private comment).

thanks in advance.

Yes, it reproduces with any model.
I just created a model with 2 tables, added 1 col to each, forward-engineer ok.
Then I added one more col to each and repeated forward-engineer - fail.
I'll attach that model.

Simple model that reproduces

I still can't repeat with your model file and new instructions.

Any other ways to trace the error? Debug version, maybe?

Hi Andrey,
can you add the output of your WBs help->system info menu.
in addition to that please check whether the problem appears the same when using the feature file->export->forward engineer SQL CREATE script

System info:
MySQL Workbench CE for Linux/Unix version 5.2.34
Configuration Directory: /home/undera/.mysql/workbench
Data Directory: /usr/share/mysql-workbench
Cairo Version: 1.10.2
Rendering Mode: OpenGL is not available on this system, so Native is used for rendering.

CPU: 2x Intel(R) Core(TM)2 Duo CPU     P9600  @ 2.53GHz 2535.000 MHz, 3,4 GB RAM

I tested with "file - export", the issue is not appeared. I pressed Ctrl+G immediately after successful tests with export - the issue is there.

Tried now on Fedora and Windows Vista and still not repeatable.

Also I noticed that before I see empty script field, after pressing Ctrl+S the '*' sign near file name in title bar doesn't disappear.

Please, check if the same problem still happens with a newer version, 5.2.35.

I tried new version, I still see empty Forward Engineer SQL code, but now application do not crash if I close EER tab.

Same problem here, but sometimes it crashes when closing EER tab, some other times while still working on that tab, apparently not on a same operation (as i recall, once while adding a table, another time when editing a foreign key, and i cant remember others)

Seems 5.2.36 fixed the issue
