Compile the following code at -O -g -mstrict-align and you get an ICE in
set_variable_part:
void ProjectOverlay(const float localTextureAxis[2], char *lump) {
const void *d = &localTextureAxis;
int size = sizeof(float)*8 ;
__builtin_memcpy( &lump[ 0 ], d, size );
}
----- CUT ------
Yes this code is undefined but it should not ICE.
