Simulation crashes in libstdc++-6.dll using ExternalMedia

[Alexander Täschner <A.Taeschner@…>]

I just tried the new Win32 build on Windows with an older model which workes fine using OpenModelica-v1.9.6. With omc and/or OmEdit from OpenModelica-v1.10.0-dev-655-gcf561f7-32bit the simulation crashes with Access violation in libstdc++-6.dll.

A total file and the used version of the ExternalMedia library is attached in the zip file.

[Alexander Täschner <A.Taeschner@…>]

Save total of the model and used lib.

[Adrian Pop]

My feeling without testing is that libExternalMediaLib.a (which was compiled using gcc 4.4) needs to be recompiled with the new gcc 5.3 from OpenModelica-v1.10.0-dev-655-gcf561f7-32bit/tools/msys/mingw32.

[Adrian Pop]

Seems that you're using coolprop with ExternalMedia, did you compiled it yourself, which version?

[Alexander Täschner <A.Taeschner@…>]

I used the precompiled version from Github(​https://github.com/modelica/ExternalMedia/tree/06b89b59fe3b17bf42062ec1bd23a3f8eda0396a) - with newer Github versions I had convergence issues with my problem. The only change is, that I defined an own HeliumMedium package with pre evaluated constants to make it faster.

[Adrian Pop]

The problem is that I need to recompile libExternalMediaLib.a with the GCC 5.3 we're now
using in OpenModelica and for that I need some version of the CoolProp sources (the master
from ​https://github.com/CoolProp has already too many changes to work with the sources from ExternalMedia). I'll ask Francesco what's the proper way to do this.

As far as I remember the already compiled libExternalMediaLib.a in ExternalMedia includes CoolProp inside it but things have changed quite a bit since then and CoolProp is separate now.

[Alexander Täschner <A.Taeschner@…>]

As far as I could see from the subversion repo of ExternalMedia, the corresponding Coolprop files came from ​https://github.com/ibell/coolprop. Comparing the dates I would guess that it was build with the 4.2.3 release (​https://github.com/ibell/coolprop/tree/43ed8a1f6093857d37d4c4838196c8d8ef9aec11).

[Christoph <buchner@…>]

Apparently, the coolprop devs maintain their own, recently updated, copy of ExternalMedia ​here, maybe this should be used instead/in addition, or re-unified with the Modelica version?

[Adrian Pop]

libExternalMedia.a compiled with gcc 5.3 32bit/64bit

[Adrian Pop]

@Alexander: can you try to update the Resources directory inside ExternalMedia with the one attached?
I now compiled libExternalMedia.a with the GCC 5.3 for both win32 and win64.
You could also try and see if OpenModelica 64bit works now with the win64 libExternalMedia.a.

[Adrian Pop]

Myself I tried with the 64bit OM and the latest ExternalMedia from:
​https://svn.modelica.org/projects/ExternalMediaLibrary/trunk/
but got some convergence issues, I guess the ones you mentioned:

Yes, I sow that. I will try to compile with CoolProp5 and see how is going but Francesco told me there were some bugs in it, so we'll see.

[Christoph <buchner@…>]

Alright. It probably makes sense to unify the 3 different versions/repos (github/coolprop, github/modelica and svn.modelica) into one definitive repo.

Btw, Coolprop 6.0 is already ​out, maybe even try with that one?

I just tried your compiled library with the 32bit version above. The simulation crashes again, but this time inside the simulation executable with a strange error (looking in the generated mini dump):

Yes, this is the same problem I encountered before. I have absoluteley no idea why the temperature value of 2.1768 is used (the helium starts in the pipes with an temperature of 4.49 K and is heated in the pipes - without heating/or with extremely low heating power the convergence issue disappeared).

Ah, I forgot I updated my GCC locally to 5.4, maybe that's the problem. I'll redo this with GCC 5.3 and upload a new Resources.zip.

[Adrian Pop]

@Alexander: you can try with the new one: https://trac.openmodelica.org/OpenModelica/attachment/ticket/3981/Resources-gcc-5.3-EMr7886.zip
This one is really compiled with gcc 5.3 but I also use revision 7886 of ExternalMedia (so that you don't get conflicts between the Modelica library and the C library if I use the latest version).

[Alexander Täschner <A.Taeschner@…>]

Using your newly compiled version (thank you very much for your efforts!) I sadly get the same exception:

Unhandled exception at 0x00DBC47A (SIS100ProportionalSafetyValveLowPressure_total.exe) in WERB342.tmp.mdmp: 0x40000015: %hs.

0x40000015 seems to be STATUS_FATAL_APP_EXIT and is generated by abort() commands. Any ideas how to proceed?

[Alexander Täschner <A.Taeschner@…>]

I just tested your new version with the 64bit omc (OpenModelica-v1.10.0-dev-660-gc1cac0c-64bit). With this the simulation shows the convergence issues (inside CoolProp) described above, but no crash.

Milestone moved to 1.12.0 due to 1.11.0 already being released.

[Francesco Casella]

See updates on ​https://github.com/modelica/ExternalMedia/wiki, and please report if this is still a problem after we issue the next release of ExternalMedia.

Rescheduled to 1.14.0 after 1.13.0 releasee

[Adrien]

Hello everyone,

Has anybody found a way to make ExternalMedia library work properly with recent OpenModelica versions (1.12) ?

Thanks a lot,
Adrien

[Francesco Casella]

It's been on my to-do list for quite some time, but I had higher priority stuff to do. I will have to solve this issue by the end of February, because I need it for a project. Please follow the progress on ​GitHub

[Francesco Casella]

Releasing 1.14.0 which is stable and has many improvements w.r.t. 1.13.2. This issue is rescheduled to 1.16.0

[Francesco Casella]

Retargeted to 1.17.0 after 1.16.0 release

[Francesco Casella]

Retargeted to 1.18.0 because of 1.17.0 timed release.
