error: cannot pass an argument with a user-provided copy-constructor to a device-side kernel launch

When compiling the dynamic mandelbrot example, I get the following error:

nvcc -O3 -arch=sm_35 -DSKIP_PNG_WRITING --relocatable-device-code=true \
	-Xcompiler -Wall -Xcompiler -fopenmp mandelbrot.cu pngwriter.o -o mandelbrot -lpng

My system specs follow:

• GPU: TITAN X
• NVIDIA Driver: 396.37
• CUDA 9.2.148
• OS: Ubuntu 16.04 LTS with kernel: 4.4.0-130-generic

Kernel optimization exercise freezes system

When I execute the profiling command nvprof -f --analysis-metrics -o metrics.nvvp ./a.out of the kernel optimization exercise, my system simply freezes. The first time this happened, the system simply became unresponsive and disconnected (I was on a remote connection). The second time it happened, I got logged out (i.e. the system was still operational).

My configuration:

• GPU: TITAN X
• NVIDIA drivers: 396.37
• CUDA version: V9.2.148
• OS: Ubuntu 16.04.4 LTS with the 4.4.0-130-generic kernel
