--- Comment #8 from Thomas Schwinge <tschwinge at gcc dot gnu.org> ---
I found that the '-O2' ICE 'during IPA pass: cp' originally reported here as
well as the '-O0' ICE 'during RTL pass: expand' do disappear with Julian's
recent r13-2665-g23baa717c991d77f206a9358ce2c04960ccf9eea "OpenMP/OpenACC
struct sibling list gimplification extension and rework".

I can't tell if Julian's commit indeed does fix the underlying problem, or =
if
it just hides it.  However:

ges
re 'PARM_DECL's, but also changes in the 'map' clauses.  It seems as if the
latter may be mandating the former, but I've not looked in detail.=
