what(): failed to close cu context (0): Invalid argument

[moore-ch]

Hi, XRT team,

in edge, I encountered one issue when xrt::kernel deconstruction, please help on this, thanks!

1. my usage: my class has members in sequence: std::map<std::string, DeviceObject> cu_handles_; // components for each cu and struct DeviceObject has member: std::shared_ptrxrt::device device; std::unique_ptrxrt::kernel kernel; std::unique_ptrxrt::ip ip; the initialization in sequence: auto device = std::make_sharedxrt::device(deviceIndex); ............some other codes.................. cu.device = device; cu.kernel = std::make_uniquexrt::kernel(*device, device_uuid, cu_name); cu.ip = std::make_uniquexrt::ip(*device, device_uuid, cu_name);
2. all the device operations are correct like load xclbin and get some registers.
3. but when ~DeviceObject(), there occurs an exception: terminate called after throwing an instance of 'xrt_core::system_error' what(): failed to close cu context (0): Invalid argument
4. the stack is as below: #0 0x0000fffff7ba7c58 in ??
