hmm, well with your patch the loop breaks out after the erase ( and no 
further increment on the iterator will take place )  so that sounds like 
your patch isn't being used

seems you came to the same conclusion :-)

still I see with the debug build that I did that I can't reproduce this, 
seems that for me _GLIBCXX_DEBUG isn't set. Just from my future 
reference what did you pass to configure ? ( I just passed the 
--enable-debug )
