It is fair to say that some projects are rather more concerned about
preserving ABI compatibility than others; the GNU C Library (glibc) project
stands out even among those that put a lot of effort into preserving
interface stability,
So it may be a bit surprising that a recent glibc change is being
blamed for breaking a number of applications, most of which are proprietary
games. There is, it seems, a class of glibc changes that can break
applications, but which are not deemed to be ABI changes.
