Some additional details jeremy provided:

Essentially, the result is that backtraces in gdb won't (necessarily)
work and that any app which calls backtrace() is likely to segfault.
There are a few other potential ways that things can go wrong, but
suffice to say that, yes, binary packages built in the window will need
to be rebuilt :-/

Well, here they are. The current plan is:

- do another mass rebuild for all those packages that might be affected.
That means: all arch packages that were build from Sept. 8 until Sept.
26 -/+ some hours for safety
- let a script (
?) increase release, commit, tag and queue the build of all effected
packages. Someone from FESCo (probably c4chris) will handle that.
- we start on Wednesdays evening (CEST)
- we hereby encourage maintainers to queue the rebuilds of their stuff
of their own before Wednesdays evening

Sorry for the trouble.
