Okay, so here's an test case that currently ends with an
OutOfMemoryException in SPARQLer and Twinkle:
SELECT ?x
WHERE {
{} UNION
{
{} UNION {}
}
}
I'm not sure why it's happening - but it's obviously being evaluated
different to my previous example (without the extra level of curly
braces) and it should be trivial to work out.
