--- Comment #5 from Thomas Schwinge <tschwinge at gcc dot gnu.org> ---
ACK, thanks for the report and initial analysis.

Not sure if this is actually supposed to be valid or invalid code (but of
course we shouldn't ICE either way).  That GCC 9 accepts this doesn't mean too
much, given that we don't know what it's supposed to mean.  Until the
interactions between OpenACC and OpenMP 'target' get defined properly, I
suggest we make this a compile-time error.  I'm testing a patch.  (Not sure if
a variant of that will be worth backporting to release branches, too?)
