Example of (tested) PNlib crashes on Win7

[Lennart Ochel]

Apparently, libsundials_idas.dll is missing from the OM installer.

[Lennart Ochel]

Well, it seems that the dll exists in OpenModelica1.13.0-dev-64bit/bin, but is not found when a simulation executable is executed.

Everything works fine with v1.12.

[Lennart Ochel]

There is still something fishy, but it is not related to the dlls.

[christoph.brinkrolf@…]

Compilation of PNlib.Examples.ConTest.PCtoTC is successful.
Using OMEdit i get:

Compilation process finished successfully.

Simulation then crashes without any helpful message, given output is:

OpenModelica 1.12. stable release is working fine for me, but (current) nightly v1.13.0-dev-354-gc5ca0a5 (64-bit) preduces this error.

gdb tells me this:

[Lennart Ochel]

This need to be fixed for the next release.

I guess the issue has been introduced with ​OMCompiler/cbe247e.

Replying to lochel:

Yes, you are right. After reverting ​OMCompiler/cbe247e, the PNlib example is working again.

[Lennart Ochel]

This is fixed now.
