It's probably worth giving valgrind a look in on this (if you find 
yourself bored with nothing to do...) 

For example I was able to use an older dietlibc with gentoo's hardened 
compiler, then I got a bunch of problems after upgrading to newer 
vserver-utils (only), this was finally resolved by compiling the same 
old dietlibc which had not caused problems previously with a vanilla 
compiler (and also the utils themselves with vanilla).  So it could 
actually be something subtle in some specific dietlibc function which 
wasn't being used previously and it might actually be a real bug?
