That's interesting as I recently looked into a similar problem and tracked it down to the use of the wrong algorithm for symbol lookup, see http://sourceware.org/bugzilla/show_bug.cgi?id=11198 . This particular issue has been fixed in the mean time in gdb. I wonder whether our problems are related, and if so, how such completely different solutions can be possible. Could you do me a favour and check whether uninstalling the libc6-dbg package and using a recent gdb from CVS also fixes your problem? Andre' PS: Of course we can add the hint to the FAQ. _______________________________________________ Qt-creator mailing list [email protected] http://lists.trolltech.com/mailman/listinfo/qt-creator
