java.lang.AssertionError: Value of variable is undefined (null). Variable reference $saxon:current24880015
100%
Description
A NullPointerException (wrapped as an AssertionError) occurs when referencing the current() function inside the predicate of a template match pattern.
Test case supplied by Olivier Jeulin on support (at) saxonica.com on 2012-04-10.
Reported against 9.3.0.5; bug still present in current development branch.

This one is proving quite troublesome. It is caused by using current() in both branches of a union pattern. The calls to current() are replaced by variable references, which refer to a variable binding that is established on entry to pattern.match(), but this mechanism is not coping with the way that a union pattern is split into two separate patterns to handle the XSLT requirement that a template rule with a union pattern is equivalent to two separate template rules, each using one branch of the pattern. The bug has almost certainly been in the product "for ever".
