when return implicitly declared array from inside a CFIF with a CFELSE will cause an incorrect return value.
in the code below, function test4 will return 0,0 on CF2016 with applied update 12. other server with applied update 6 returns 2,0. function test3 is identical except it has no else statement, works the same on both.
<!--- works as expected --->
<cffunction name="test3">
<cfargument name="a1" type="string" required="true">
<cfset var x = 0>
<cfset var y = 0>
<cfif a1 gt 1>
<cfset x += a1>
<cfreturn [ x, y, "", "" ]>
</cfif>
<cfreturn [ x, y, "", "" ]>
</cffunction>
<!--- doesnt work --->
<cffunction name="test4">
<cfargument name="a1" type="string" required="true">
<cfset var x = 0>
<cfset var y = 0>
<cfif a1 gt 1>
<cfset x += a1>
<cfreturn [ x, y, "", "" ]>
<cfelse>
<cfset x += a1>
</cfif>
<cfreturn [ x, y, "", "" ]>
</cffunction>
<cfset x = test3(2)>
<cfoutput>#x[1]# #x[2]# #x[3]# #x[4]#</cfoutput>
<br>
<cfset x = test4(2)>
<cfoutput>#x[1]# #x[2]# #x[3]# #x[4]#</cfoutput>
<br>
<cfset x = test4(1)>
<cfoutput>#x[1]# #x[2]# #x[3]# #x[4]#</cfoutput>
