Crash in xsl:iterate - Internal error: no value for variable $word at line 27 of .....xsl
100%
Description
The variable in question is an xsl:iterate parameter.
The code is using Evaluator.SINGLE_ITEM which should only happen with a cardinality of exactly-one, but it seems the cardinality is zero-or-one.
Stylesheet attached; any source document will do.

9.7 correctly fails saying "An empty sequence is not allowed as the second argument of map:get()".
Updated by Michael Kay over 7 years ago
The problem is that the expression map:get($histogram, $word) is being loop-lifted out of the xsl:iterate instruction for which $word is a local parameter. This is because the expression that binds $word (the LocalParam) is not an ancestor in the expression tree of the variable reference.
Fixing this in VariableReference.getScopingExpression()
