What software would that be?

I frequently run into requirements for more recent versions of the 
compilers and other build tools on Centos 6 (or 7).  These are typically 
resolved using either devtoolset or by upgrading builds of things like 
cmake or automake and installing them in /usr/local or my home 
directory.  Requirements for newer boost versions are distressingly 
common, and that is much more of a problem because it is often hard to 
coerce the build tools to use it even when one is available. (I'm 
looking at YOU cmake.)  There is a 1.57 RPM somewhere or other for 
Centos, and so far that has always sufficed.

But I don't recall ever needing a newer glibc or glibcxx.  Doing that 
would be a huge mess unless the code used no other libraries - because 
all other common libraries on the system would be linked against the 
system version.

Safe if no other libraries are involved.  See what "ldd" shows.  If 
there are other libraries, and they have dependencies on the old version 
of the newer one you installed, it would be a problem.
