OMEdit crashes under Windows

[rfranke]

Using 1.9.1b2 or nightly 3/18, OMEdit crashes under Windows 7 Pro with:

1. start OMEdit.exe
2. open Modelica library by clicking on respective +-sign in Libraries pane -- the package icons are just grey without graphics!?
3. open Blocks by clicking on the respective +-sign
4. open Continuous by clicking on the respective +-sign

OMEdit.exe crashes.

Doing the same under Debian Wheezy, the package icons are filled with the respective graphics and no crash occurs.

I can't reproduce this error on Windows 7 Professional.

I need log files,
%TEMP%/OpenModelica/OMEdit/omeditcommands.log
%TEMP%/OpenModelica/OMEdit/openmodelica.omc.output.OMEdit

The crash repeated with nightly 3/19. Find attached the requested log files.

I see that you have +a flag enabled.

+a, +keepArrays            Sets whether to split arrays or not.

This is changing the result of all annotation APIs. I am not sure if this flag is suppose to change the results. I have added few more developers in the CC list how might know more.

If you don't need this flag then simply run OMEdit and then go to Tools->Options->Simulation and set OMC Flags to empty.

The +a flag is rather experimental and should not be used by default.
Especially it should not be used for anything but flattening.
It doesn't think it will even work for simulation.

[adrpo]

I guess we should disable the +a flag at least when we evaluate annotations.

[adrpo]

I disabled +a when dealing with annotations in r19647.
This might fix the issue, but really +a should not be used interactively.

[rfranke]

Disabling +a in OMEdit seems to solve all my issues:

• The package icons show in the Libraries pane
• Browsing to Modelca.Blocks.Continuous works
• Check of AlgorithmicModel.BaseModelAlgorithm is still fast
• I can simulate the examples in AlgorithmicModel

Great. Thank you!

(Just translation of the models is slow -- looking forward to eventually seeing some improved +a flag :-)

[rfranke]

Just for completeness: ClickClickCrash.png shows a screenshot with +a flag: the package icons don't show up in the Modelica library and attempting to browse into Modelica.Blocks.Continuous leads to the crash (read from memory location 0 in QtGui4.dll).

Did you fix the crash if +a was enabled, Adeel?

[adeas31]

Adrian fixed it r19647.

That still does not fix OMEdit crashing if it is fed improper input... It must never crash regardless what stupid things omc sends back.
