  IIRC this somewhat happened no ;-)
  Except early testing before releases I don't see how to avoid such problems.
We have seen this with programs and libraries using non-public entry point
of glibc, and either you can fix the callers and make a synchronized new
release or you have to keep a compatibility library.

  The point IMHO is rather common testing. I'm pretty sure libxml2/libxslt
code I commit will be tested immediately by the Gnome users, and will
be tested by my Windows user base after the next official release, but
sometime it takes a few releases before I get noticed of a KDE breakage.
My conclusion is that the key point is homogeneous and as early as
possible testing, one of the thing to avoid is for example to keep 
a separate copy of such lib into another project CVS base unless it's
updated on a daily basis.
