The problem affecting the Fedora Extras RPM is still there with the
new compilers though:

 -Wp,-D_FORTIFY_SOURCE=2 

combined with -O or -O2 causes a strange printing bug:

> matrix(list(pi))
     [,1]
[1,]

(You don't have to use that option of course, but it suggests that not
all is well with the optimizer. And the Fedora maintainer seem set on
using it, which is a bit of a problem.)
