g++-11.0.0-alpha20201025 snapshot (g:308e40331f9d2820f8286769b5fc764671187364)
ICEs when compiling the following testcase, reduced from
test/CodeGenCXX/copy-constructor-elim-2.cpp from the clang 10.0.1 test suite:
struct pq {
pq (const pq &);
};
struct a9 {
operator pq () const;
};
struct zp : pq {
zp (const a9 &k3) : pq (k3) { }
};
% g++-11.0.0 -c oowewmvl.cpp
oowewmvl.cpp: In constructor 'zp::zp(const a9&)':
oowewmvl.cpp:10:29: internal compiler error: in build_over_call, at
