Segmentation fault (core dumped) during infer_request->Infer() or async_infer_request->StartAsync()

[You__Song_Shan]

I am writing a Mask-RCNN demo to take camera images as a video stream.

Segmentation fault (core dumped) when running either of these:

• infer_request->Infer()
• async_infer_request->StartAsync()

gdb output:

Thread 6 "segmentation_ma" received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7fffd8904700 (LWP 9000)]

Environment:

• OpenVINO 2019 R3
• Ubuntu 16.04

You may want to take a look on mask_rcnn_demo application in open_model_zoo (it also available in your OpenVINO install folder, across other demo applications)

Thanks for the reply. In fact, I am actually taking reference on the mask_rcnn_demo application, but I still do not know how to debug this segmentation fault since it is happened inside the infer() or startAsync() API call. May I know what are the suggested steps to debug this?

Any update on this? I really need help on this.
