The problem occurs when the only reference to a local variable is in the initializer (select expression) of an xsl:param within an xsl:iterate instruction. The optimizer is attempting to inline the local variable (replace the variable reference with its value) but the xsl:iterate instruction is not passing on the request. This can also happen where a variable reference being inlined appears in the "on-completion" part of the instruction.
A workaround in this example would be to prevent inlining of the variable by including a dummy reference to the variable that doesn't affect the outcome, e.g. if ($X) then () else ().
A patch is in Subversion ready for the next maintenance release on the 9.4 branch.
