The root cause is in func.c, FuncDeclaration::semantic(Scope *sc)

Around line 240, we read:

    sd = parent->isStructDeclaration();
    if (sd)
    {
    if (isCtorDeclaration())
    {
        return;    // <============== this is a problem!
    }

Returning at this point means that the scope isn't saved. This prevents the
later semantic passes from running, in certain cases. Commenting out the return
prevents the ICE. I haven't yet checked this patch on the test suite, it could
be that additional changes are required. But the problems begin here.
