DESCRIPTION:
After compiling AADL code with
ocarina -aadlv2 -y -b -g polyorb_hi_c xx.aadl
I get an executable that I can run but I get a segmentation fault error and result.csv file is 0 bytes.

./xx_sys_impl/actuator/actuator

Segmentation fault

This model contains 5 FMUs generated in OpenModelica. Unfortunately the full model can't be shared so is there any way that I can debug that error?

Thanks

Can you compile with debug activated and use gdb to know where the error is ? It may either be in the FMU wrapper itself, or PolyORB-HI/C. I suppose it is the FMU wrapper itself, but cannot guess without further details.

[svenTeum]

This is the gdb output after compiling with -d flag. I'm not sure if it gives useful information.

Have you tested any FMUs generated with OpenModelica?

[yoogx]

Cannot remember from the top of my head wether we tested OpenModelica or JModelica
openaadl/fmu2aadl repository has the examples we tested

[svenTeum]

Yes, I saw that those are from JModelica so that's why I asked. Since I found some issues with Amesim created FMUs, there may be some issues with OpenModelica ones as well I guess.

The following patch addresses the issue when using FMUs generated by OpenModelica
