Problem Description: A 'perfect storm' of syntax in CF 9.0.1 can cause coldfusion to execute a function twice and ignore the line preceding the function call.

Steps to Reproduce:

Create a simple function that accepts a struct:
public void function SimpleFunction1 (struct incomingStruct) {
	WriteOutput("This is SimpleFunction1.<BR />");

Call that function with a named, inline struct shortcut:

Works fine so far. Now, wrap that function call in a try/catch block:
catch (any e){

Finally, add an instruction above the function call:
        abort; //this command will fail to execute
	SimpleFunction1(incomingStruct={item1="ok",item2="go"});//this function call is executed twice
catch (any e){

Actual Result:
In spite of the abort, the following output will appear on screen:
This is SimpleFunction1.
This is SimpleFunction1.

Expected Result:
The function should execute once. The line preceding the function call should not be ignored.

Any Workarounds:
There are many:
* Don't use a named parameter, just pass in the struct shortcut.
* Assign the struct to a variable and pass the variable in the function call.
* Remove the try catch block

I have not tested this on 9.0.2, 10, or 11

same on 9.0.2 example: <cfscript> public void function SimpleFunction1 (struct incomingStruct) { writelog(application = true, type = "information", file = "sean", text = "This is SimpleFunction1."); } writelog(application = true, type = "information", file = "sean", text = "starting..."); try { writelog(application = true, type = "information", file = "sean", text = "about to call function..."); //this line will never execute. SimpleFunction1(incomingStruct = { item1 = "ok", item2 = "go" }); //this function will execute 2x writelog(application = true, type = "information", file = "sean", text = "function called..."); } catch (any err) { rethrow; } writelog(application = true, type = "information", file = "sean", text = "complete..."); </cfscript>

+1 not good to have functions executing twice just because its taking an inline struct and is not the first line in a try/catch

Verified this is fixed in CF10 Update 14 (10,0,14,291717) and CF11 Final (11,0,0,289822). The command before the function call is executed and the function call is executed once. Thanks!, -Aaron
