Problem Description:
The error message "Routines cannot be declared more than once" is being shown for a function that is included twice with runonce="true" specified both times.

This problem does not occur using Lucee.

Steps to Reproduce:

Here is a short test case of 4 files that reproduces the problem.

<!--- /index.cfm --->
<cfset createObject("component", "component").init()>

<!--- /component.cfc --->
	<cffunction name="init" output="true">
		<cfinclude template="file_that_depends_on_message.cfm" runonce="true">
		<cfinclude template="message.cfm" runonce="true">
		<cfset message("component")>

<!--- /file_that_depends_on_message.cfm --->
<cfinclude template="message.cfm" runonce="true">
<cfset message("file that depends on message")>

<!--- /message.cfm --->
<cffunction name="message" output="true">
	<cfargument name="value" type="string">

Actual Result:
The error message "Routines cannot be declared more than once."

Expected Result:
"file that depends on message

Any Workarounds:
Using cfscript, the function can be defined anonymously and assigned to a variable.
	 variables.message = function(value) {



I started using the "runonce" parameter now that we've upgraded most of our projects and I ran into this error too. So it 1) either doesn't work as documented or 2) I must have a different understanding of what "run once" means. I've been using this workaround since ColdFusion 8 and guess I'll continue to use it to prevent this compilation error from occuring. <CFPARAM NAME="Request.RunOnce" DEFAULT="0"> <CFSET Request.RunOnce = VAL(Request.RunOnce)+1> <CFIF val(Request.RunOnce) IS 1> <CFINCLUDE TEMPLATE="./Site_Specific_UDFs.cfm"> </CFIF> The "runOnce" feature was introduced in CF10. I see that it was reported in CF11 alpha. I encountered it in CF2016u10 as I figured two (2) release versions would mean that it would be safe to use. It has a "normal" priority with a "to fix" status. CF11 is EOL in 5 days (April 30, 2019). Are there any plans to fix this in CF2016, CF2018 or an unannounced, yet-to-be-released version?

I didn't know that this option existed, but encountered this bug the first time I used it.
