More accurately, it is a problem with the C++ runtime support that is
installed. There are complications here depending on which Linux
distribution you are using, whether or not you have upgraded the gcc
installation yourself, ... I have not seen the symbol size warnings
before but I suspect that they are harmless. If ecosconfig starts
SEGV'ing on you than that is an indication that C++ exception handling
is not working and that you need to rebuild ecosconfig from source.

Another thing worth trying is "ecosconfig list". That will tell you
about all the packages and targets, in your current eCos repository.
