Hi,

I thought it is worth looking into the C++ code completion problems I=20
encounter with kdevelop from the KDE 3.5 svn branch.

To reproduce the problem it is necessary to remove all old pcs-files from=20
$KDEHOME/share/apps/kdevcppsupport and to start kdevelop with a C++ project=
=2E=20
=46rom the project options create a new pcs file for Qt.=20
Set the cursor at the end of a line in the editor press enter and then any=
=20
letter. kdevelop goes into an infinite recursive loop starting in=20
languages/cpp/cppcodecompletion.cpp, line 1990.

I have modified lib/catalog/catalog.cpp with the attached patch and this=20
solves the infinite recursion of kdevelop. Code completion seems to work=20
however I do not have enough time right now to test the patch thoroughly an=
d=20
I have to admit that I don't know what I am doing. ;-) (Anyone daring to te=
st=20
the patch?)

As a side note: during the error hunting I had the impression that the=20
pcs-files are corrupted and unusable if kdevelop is started from a console=
=20
and stopped via Ctrl-C.

Have fun,
Jens

PS: BDB seems to be version 4.2.52
