[$] The ABI status of ELF hash tables

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