glibc-2.14.90-12.999 also breaks the build of ANY C++ code using fenv.h, 
which affects at least Qt (but likely also several other C++ packages, 
particularly mathematical ones, but not only, as can be seen from Qt). 
Thankfully, that showstopper is fixed in -13 which is already in stable by 
now (because it was aggressively up-karma'd by the KDE SIG).

The fact that a glibc with showstoppers of this kind got pushed to stable 
shows that the karma system does not work at all. It just hinders getting 
legitimate fixes out and does nothing to stop regressions. glibc is even 
critpath, yet broken crap still goes out.
