Bug#665714: iceweasel: consumes vast amount of RAM and swap when gcc 4.7 installed

[Arthur Marsh]

Package: iceweasel
Version: 11.0-3
Followup-For: Bug #665714

I downgrade libgcc1 and still ran into the problem:

26124 amarsh04  20   0 1828m 1.2g  36m R 146.4 15.3  65:00.73 firefox-bin

i.e. 146.4 percent CPU use on a 4-core machine.

Disabling javascript for twitter.com seemed to reduce the problem.
