In the past 2 days, I was in trouble handling a program crash dump which uses CUDA:
(gdb) bt
#0 0x00007ffff73fc559 in cudart::globalState::registerEntryFunction(void**, char const*, char*, char const*, int, uint3*, uint3*, dim3*, dim3*, int*) () from /home/xiaonan/dl2-he/3rdparty/libDSI_FV.so

Long story to short, my OS is Ubuntu 16.04.5 LTS, and CUDA version is:
$ nvcc -V
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2017 NVIDIA Corporation
Built on Fri_Sep__1_21:08:03_CDT_2017
Cuda compilation tools, release 9.0, V9.0.176
After tough trial and error, the solution is renaming one file from “.cpp” to “.cu“. But on another Arch Linux with the newest CUDA (V10.0.130), this problem doesn’t exist.
