Subject: [Bug c++/53094] constexpr vector subscripting
Date: Mon, 03 Dec 2012 22:05:00 -0000 [thread overview]
Message-ID: <bug-53094-4-5DiH8CAPSD@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #12 from vincenzo Innocente <vincenzo.innocente at cern dot ch> 2012-12-03 22:05:29 UTC ---
about subscripting I get an ICE (set fault)
with
constexpr V4 v = {1,1,1,0};
constexpr V4 m[3] = { (V4){1,0,0,0}, (V4){0,1,0,0}, (V4){0,0,1,0}};
constexpr V4 r = v[0]*m[0] + v[1]*m[1] + v[2]*m[2];
constexpr V4 r = v[0]*m[0] + v[1]*m[1] + v[2]*m[2];
