implicit struct/array breaks <cfelseif> (no issue in script; issue exists only in tag)
The simplest index.cfm example is: (Throws "Variable ___IMPLICITARRYSTRUCTVAR0 is undefined.")
-----------
<cfif false>
<cfelseif isStruct({foo="bar"})>
</cfif>
-----------
This simplest Application.cfc example is: (Throws "Could not process Application.cfc successfully for template C:/path/to/index.cfm.")
-----------
<cfcomponent>
<cfset THIS.name = "ticket_ImplicitStructArrayBreaksCFElseif">
<cffunction name="onRequestStart">
<cfif false>
<cfelseif isStruct({foo="bar"})>
</cfif>
</cffunction>
</cfcomponent>
-----------
However, here are some more realistic repro cases:
1) Does not display "foobar" (bug) and logs "Accessing value from uninitialized register" to coldfusion-out.log:
