Hi,
we've been encountering an ICE for OpenACC host_data sections, which
has a use_device() clause similar to OpenMP use_device_ptr.
The ICE happens in make_decl_rtl() for scan-created variables, which IIUC,
should not be entered at all for automatic variables.
I believe the problem is, unlike
Ping.

Hi Thomas,
this fix adds more acc_wait's to libgomp.oacc-fortran/lib-1[13].f90.
For lib-12.f90, it's sort of a fix before we can resolve the issue
of intended semantics for "wait+async".
As for lib-13.f90, I believe these added acc_wait calls seem
reasonable, since we can't immediately assume
The OpenACC wait directive is represented as a call to the runtime
function "GOACC_wait" instead of a tree code. I am seeing when
