--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
flags?  A simple ./xgcc -fopenacc doesn't reproduce it.  With my GCC 7 install
I see

lto-wrapper: fatal error: problem with building target image for nvptx-none

but no way to see the lto1 invocations :/ (tried -Wl,-debug -Wl,-v already)
