Produces the error:

```

```

This also compiles fine to a 23MB release build binary. It seems the `Expr` expansion of a match is not feasible. Each condition is causing a full branch which includes all cases below it. For example consider:

```fsharp

open FSharp.Quotations

let count n q =
let rec loop q =
match q with
| Patterns.Value((:? uint64 as x),_) when x = n -> 1
| ExprShape.ShapeCombination(a, args) -> args |> List.sumBy loop
| ExprShape.ShapeLambda(v, body) -> loop body
| ExprShape.ShapeVar(v) -> 0
loop q

<@
match None, Unchecked.defaultof<_> with
| None, {A = true; B = Q; C = Q} -> 1UL
| _ -> 100UL
@>
|> count 100UL
```

Here the `100UL` branch gets counted 4 times, With

```fsharp

<@
match None, Unchecked.defaultof<_> with
| None, {A = true; B = Q; C = Q} -> 1UL
| None, {A = true; B = Q; C = Q} -> 2UL
| _ -> 100UL
@>
```

the `2UL` branch now counts to 4 and the `100UL` branch is now at 16. This quickly explodes with relatively simple match blocks.
