Why a try/catch in priority_queue::push/pop?!?

I see... But I can find the strange beast already in libstdc++-v2, in 
gcc2.95.3, a *lot* of time! (admittedly I never played myself with the 
original HP/SGI STL, as distributed from the SGI web site, for example, 
only some friends of mine did...)

Ok, thanks a lot for your reply. Then, for the time being, I think I 
will simply remove the try/catch, then we'll see...
