Update to gcc 4.7 causing problems RVM Ruby 1.8.6

Hello,
I have just encountered a problem rebuilding my rvm platform. The
version of gcc4.7 causes the ruby build to not work properly. Rebuilding
with gcc 4.6.3 and everything is ok.

This is since the current gcc has been updated to 4.7.0.

$ gcc -v 2>&1 | grep "gcc version"
gcc version 4.6.3 (GCC)
$

$ rvm install ruby-1.8.6-p420
$ rvm use ruby-1.8.6-p420@rails-2.0.2 --create
$ gem install rails --version=2.0.2

All ok.

$ gcc -v 2>&1 | grep "gcc version"
gcc version 4.7.0 20120407 (prerelease) (GCC)
$

$ rvm install ruby-1.8.6-p420
$ rvm use ruby-1.8.6-p420@rails-2.0.2 --create
$ gem install rails --version=2.0.2
/usr/local/rvm/rubies/ruby-1.8.6-p420/lib/ruby/1.8/timeout.rb:59: [BUG]
Segmentation fault
ruby 1.8.6 (2010-09-02) [x86_64-linux]

I've reverted to gcc 4.6.3 for the time being. Just in case this is of use to anyone sd gcc 4.7 seems to have introduced a problem.
