Can you share some code? You don't want to use try-catch?

Here is minimal example that illustrates this:
=====================
import std.stdio;

void do_assert() { assert(false); }

void stackFrame()
{
    //pragma(inline, false);
    do_assert();
}

void main()
{
    try
    {
        stackFrame();
    }
    catch(Exception e)
    {
        e.writeln();
    }
}
=====================

Stack trace with "dmd -g -O -run test.d" command (no stackFrame 
function in it):

The question: is it possible to tell compiler to always generate 
stack frame for my stackFrame function?
"pragma(inline, false)" doesn't help here - the result is 
completely the same.
