problem is quite well documented here
http://nepenthes.sourceforge.net/documentation:readme:faq:gcc_4
dont ask mw why this applies to g++ 3.4 for ubuntu too, you run some scary patches?

Was fixed on debian some time ago in g++ 4.

artsd suffers the same problem on ubuntu
http://www.google.com/search?q=artsd+ubuntu+segfault

please fix this, currently ubuntu lacks a working compiler.
