Run-time error of OpenMP offload application

Hi,
My application runs fine when built without LLVM/Clang’s OpenMP offload options,
but segfaults at run time with them. Below is a back trace of the app, any idea
as from the trace to why the app while target clause is not embedded yet at all
crashes?
