#4807

Merged

Assertion `isLValue() && "This isn't an lvalue"' failed.

When executing: swift::SILValue swift::Lowering::ManagedValue::getLValueAddress() const

    // either +0 or trivial (in which case +0 vs +1 doesn't matter).
    return !hasCleanup();
  }

  SILValue getLValueAddress() const {
    assert(isLValue() && "This isn't an lvalue");
    return getValue();
  }
