DjiCore_DeInit segmentation fault

[biancabnd]

Hello,
First of all, thank you for maintaining and upgrading this SDK!
While using it, I found myself with the need of shutting down all modules cleanly and thus, using the DjiCore_DeInit() function.
However, the node where I launch this simply dies when I call core deinit. I thought this could be something on my end, so I tried to force the same method on the C Samples you provide. The result I obtain is the following:

Am I missing something or do I need to do something else before calling DjiCore_DeInit()? How can I avoid having the segmentation fault each time I shut down the psdk application?

Thank you in advance.

Dear Developer,

Hello, thank you for contacting DJI.

You can try to follow the order in DjiUser_CleanSystemEnvironment() function for de-initialization.

Hello.
Thank you for your answer. The screenshot I have sent you is a result of calling directly the DjiUser_CleanSystemEnvironment() function. As you can see, there seems to be a problem with the Dji_PowerManagement_DeInit, and thus the DjiUser_CleanSystemEnvironment() function fails.

Dear Developer,

Hello, thank you for contacting DJI.

Which version of PSDK are you using? We may need to further confirm this function.

Dear Developer,

Hello, thank you for contacting DJI.

Thank you for the information you provided. We have confirmed that PSDK will start related function modules when it is started. These modules may re-create threads, which will cause some resource lock restrictions when you close the main thread. May I ask what your demand scenario is? Do you want to turn off all module functions?

Thank you for your support of DJI products.

Hi again,

Yes. What I try to do is:

1. Initialize all modules (DjiCore_Init, DjiFcSubscription_Init, DjiCameraManager_Init, etc). This works perfectly.
2. Do something with the data, tests, etc - All good here
3. Shutdown the PSDK application and all modules cleanly. For this I call Deinit functions of the modules, DjiCameraManager_DeInit, DjiFcSubscription_DeInit which exit with no error. Lastly, I want to call DjiCore_DeInit() and this always makes the node die not cleanly, so with segmentation fault.

Maybe there is something else I need to stop before calling the DjiCore_DeInit() function. But I've checked DjiUser_CleanSystemEnvironment() from the samples, and this method does not exit cleanly as well.

My question is, how can I shutdown the entire PSDK application cleanly and turning off all modules?
