The 1.2 tree uses SigC signals and slots to pass info around internally. The 1.3 tree uses boost signals and slots. The problems you are experiencing are the direct result of this change. It appears that the boost signals trigger a compiler bug in gcc 2.95 and 2.96. Basically, any static signals are not initialised correctly if that part of the code is compiled with -O2 optimization. The apparent work-around is to rebuild your src tree, compiling with -O0 optimization. I believe that you can do this by running configure --enable-optimization=0, but you should look closely here yourself as I'm not au fait with this option. Hope this helps, Angus
