This whole thread made me experiment a bit, and now I'm positively confused. 
On my system / compiler (x86, Linux 2.4.7, glibc 2.2.3, gcc 2.95.3), I can't 
get more than about a tenth of a percent reduction in resident set size 
through -fno-exceptions from a couple of toy projects, regardless of whether 
the code was using exceptions originally or not. Under what circumstances 
does this overhead become noticeable? Maybe only in shared libraries?

Ciao,

Daniel.
