Description
The following query (taken from W3C FOTS:fn-function-lookup-314) causes Saxon to throw an IllegalState exception:
function-lookup(fn:QName('http://www.w3.org/2005/xpath-functions', 'unordered'), 1)(1)
The problem occurs with all "compile-time functions" - those that are normally processed entirely at compile time. Apart from unordered(), other examples include true(), false(), and static-base-uri().
The stack trace of the exception thrown is as follows:
java.lang.IllegalStateException: Function unordered should have been resolved at compile-time
