I have a situation like this ...

        writefln("ENTRY");
        // skip a whole lot of code ...
        if (some_condition)
        {
            writefln("A");
            Foo( xx );
            Writefln("B");
        }
        // blah blah blah ...

        writefln("EXIT");
   }

And the output I'm getting is ...

 ENTRY
 A
 B
 EXIT

but I was expecting ...
 ENTRY
 A
 ENTRY
 EXIT
 B
 EXIT

The code is inside a very large program so I'm a bit loathed to start
chopping it up to find the minimum program that still demonstrates the
effect. I suppose I could examine the object code to see what's being
generated but I was hoping that someone might give me a clue first.

First I'd do this void Foo(T)(T pData) { T xx; writefln("ENTRY"); scope(exit)writefln("EXIT"); [...] } That will make sure that no exceptions are messing you up.
