Compiles and runs without errors here.  I used gcc 3.4.6 on Debian 
unstable.

I haven't seen this, but it looks like mismatched libraries/compiler.  
The C++ libraries have gone through several major upgrades in the past 
few years and the libraries and compiler all have to match.  If your 
compiler and libraries are part of your distribution, looks like the 
maintainers weren't careful enough.  Look for updated packages specific 
to your distribution.
