The debug_log lead to preprocess plugin seg fault

[jiangyuzhe1992]

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU) GPU
• DeepStream Version 6.1
• JetPack Version (valid for Jetson only)
• TensorRT Version 8.2.5-1+cuda11.4
• NVIDIA GPU Driver Version (valid for GPU only) 510.68.02
• Issue Type( questions, new requirements, bugs) questions
• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)
export GST_DEBUG=5
• Requirement details( This is for new requirement. Including the module name-for which plugin or for which sample application, the function description)
When i export GST_DEBUG=5, the ds-app start to print debug log. But it make a Segmentation fault in the preprocess plugin. I add some prints , and found it may core dump at a debug log.

Here is some debug log:

I run the code in a docker image : nvcr.io/nvidia/deepstream:6.1-devel

When i found it may this log lead to core dump , i annotation this log . It can work normaly.

Wait for your answer. thanks

Which demo did you run, our demo or your own demo?
Could you help to use our demo to repro this crash problem?

@jiangyuzhe1992 , Thanks for your debugging, it’s a code error. Cause it’s open source, you can modify it by

    GST_DEBUG_OBJECT (nvdspreprocess, "parsed user-config key = %s value = %s\n", *key, val.c_str());

We’ll update it in the future version.

[jiangyuzhe1992]

thanks for your reply.
