Default GPU stream was used when MSHADOW_FORCE_STREAM was on

When I wrote my customized c++ layer, after compiling and installation.
When I use it in my code, it has the following error:
"dl-build-source-mxnet/mxnet/3rdparty/mshadow/mshadow/./stream_gpu-inl.h:82: Default GPU stream was used when MSHADOW_FORCE_STREAM was on
"

Any advice will be appreciated, thanks

The above problem has been solved, but the following error exists:

Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)

Any advice will be very appreciated, thanks
