No it was not always the case, I do not know exactly the reason, but
without the changes in most cases the line is never displayed and even
the callstack changes :-? Looks like something in the assembler window
changes the stack in someway and the offended line is no more at which
it is expected. I'll recheck my changes in order to match the real
difference once I'm getting into the debugger inners.

I know, and that's my next step if there is interest. But by now and
in order to help me in my other projects I'm using the "default"
returned format, mostly to try to understand the code and at the same
time get something usable as fast as possible.

If you have changes in your local codebase will be great to send them
to me in a diff to not overlap any work. If you are planning to
improve debugger asap I'll stop my changes and wait, as your skills
with the debugger is around 1000 times mine :)
