To be precise, you will need gcc-2.96-65 from the rawhide distribution.
However, this does not seem to have been released yet: I just checked on
ftp.redhat.com and the latest release is -64.

Alternatively you can install gcc-2.95 (the latest *stable* compiler from
the gcc development team), which does not suffer from this bug. If you want
to do this, look in the directory bin/linux/redhat/7.x/DIY/ on CRAN for
