Re: cannot subscript something of type <data variable, no debug info>

objdump isn't what you want; try "readelf -w tester".

'nm' will show the symbol 'Mod'.  The symbol is fine,
it has a valid address and everything.  The problem is that the
*type information* for the symbol is missing.

I don't know SuSE, but it sounds like you have some freak compiler
installed, all right.  SuSE must have a good compiler too, because
the SuSE system that I'm using compiles your source code to an
executable file with good debug info.

3.4.1 has some debug info regressions compared to 3.3.4.
Also since your vendor compiler is a derivative of 3.3.3,
3.3.4 might slip in a bit easier, especially if you link
against system shared C++ libraries like the KDE libraries.
