Specific tools are not discussed in this newsgroup. Your question thus is
off-topic here. A better place for it would be gnu.g++.help.
Having that said: That warning seems to indicate some missing initialization
in the implementation of std::list. The reason that you see it only with
certain optimization options is because the compiler does a deeper code
flow analysis on these optimization levels, so it simply fails to notice it
on lower optimization settings.
