Proc names in message box - inviting hackers?

Hi

I have an error handler at end of every procedure/function of my macros that returns a message box similar to following:

    MsgBox "FATAL ERROR!!!" & Chr(13) & Err.Number & " " & Err.Description _
            & Chr(13) & "Exiting program...", vbCritical, "Error"

For easy debugging, in the error I plan to hard code the proc/function name in the error message, as follows

    MsgBox "FATAL ERROR at cmdProcess_Click() !!!" & Chr(13) & Err.Number & " " & Err.Description _
            & Chr(13) & "Exiting program...", vbCritical, "Error"

Question: Will displaying proc/function names to end users make my application more vulnerable to hackers, etc?
