CEDET

Another tid-bit of information - it seems like Semantic is firing on idle
and I'm getting this error in the debug frame:

Idle Work Including Error: "#<buffer .emacs> - Wrong type argument:
number-or-marker-p, (512 39 . 8739)"

What does it mean?

Are you using CEDET on Windows? If so, I'm actually surprised you got
1.0pre6 compiled in the first place, since there were some bugs
regarding the Windows platform in that version.

Please update to the CVS version, which you can get by doing

cvs -z3 -d:pserver:anonymous@... co -P cedet

Works for me. Put the cursor behind the 'ca->' and do

M-x semantic-analyze-debug-assist

to get further output on why the completion does not work.

It means that Semantic had a problem parsing some stuff in your .emacs
file, which you probably had opened in your Emacs session. This doesn't
interfere with the C++ parsing, so that error shouldn't matter here at
the moment.

Yes, Piotr also suggested using the CVS version. I did - and it all works
now! And yes, I am using it on Windows. I didn't pay attention during the
compilation, so perhaps things did break.

Appreciate all the help guys.
