Hello,

I am having trouble using the intrule flag. I want to calculate the edge-wise integral using a higher order quadrature rule. The last line of the following code gives me a segmentation fault:

```
V = L2(mesh, order=1,dgjumps=True)
u,v = V.TnT()
a = BilinearForm(V)
ir = IntegrationRule(SEGM, 5)
a += SymbolicBFI(u*v, skeleton=True, intrule = ir)
```

Best,

Guosheng
