--- Comment #2 from Ye Luo <xw111luoye at gmail.com> ---
After a bit more investigation, I found it related with the flag -march
intended for the host compilation.
I invoke the compiler with
-march=native -O3 -ffast-math -fopenmp -fopenmp-targets=nvptx64-nvidia-cuda
some functions failed to be loaded.
If I put -march=skylake-avx512, it still fails.
Once I changed the flag to -march=skylake, my application runs.

So my hypothesis is, some avx512 codes contaminated my device functions.
