4631	FMU clash with IPython and PyFMI (JSON involved)	anonymous	Lennart Ochel	"Trying to load an FMU compiled by omc (OpenModelica's compiler) with PyFMI provoke a nasty crash under IPython.

Running

    import pyfmi
    pyfmi.load_fmu(""path/to/fmu"")
    
makes IPython crash with message
    
    JSON object expected ',' or '}', got: ""lineEnd"":67,""colSta
    Aborted (core dumped)

I tried both IPython 5.4 and 4.2, for Python 2.7.13 (Anaconda 64-bit) on Ubuntu 16.04.

An example FMU for reproducing the bug can be found here:
https://trac.fmi-standard.org/browser/branches/public/Test_FMUs/FMI_2.0/...

This seems to be specific to OpenModelica as a JModelica compiled FMU (https://trac.fmi-standard.org/browser/branches/public/Test_FMUs/FMI_2.0/...) does not trigger the error.

Both FMUs pass the FMU compliance check.

Do you have any idea about the problem's root and how to solve it?

I already experienced segfaults with older version of OpenModelica, as mentionned here: http://www.jmodelica.org/27816. They were however rare enough to be only a nuisance, not a show stopper."	defect	new	high	Future	FMI	v1.12.0		pyfmi ipython json
