That's a strange place to get the error.  I get an AV at constfold.c:1396.

CatExp::optimize calls :optimize on fileProtocol (which does nothing) then
passes it along to Cat, which crashes trying to access fileProtocol's type.

It seems to happen for all operators:

class Orbit
{
    Repository repository = Repository();
}

struct Repository
{
    //int source = xx ~ xx;
    //int source = xx + xx;
    //int source = xx - xx;
    //int source = xx * xx;
    //int source = xx / xx;
    //int source = xx ^^ xx;
    //int source = xx & xx;
    int source = xx | xx;
}

void main () {}

It is probably invalid to assume e->type has been set inside Cat and other
constfold functions.
