--- Comment #6 from Michael Schwendt mschwendt@gmail.com 2012-04-28 05:57:45 EDT --- Compiling C++ template headers results in binary code that is built into the target program. The same applies to inline functions defined in C headers. If the headers change due to a fix for a bug or for a security vulnerability, you need to recompile every program that uses the headers.
In case other -devel packages in the Fedora Package Collection also include only C++ templates, they would also need to be handled appropriately. Also, there may be some -devel library packages, where the included headers *also* define a few inline functions or template classes, and this is a little bit of a grey area, because again, important code changes in those parts require rebuilds of dependencies. Just as with a static library.
