I guess that you are using amd64 and that the problem you are seeing is due to
a difference in the memcpy implementation in libc6.
Could you try to run iceweasel or chromium in the following way:
$ LD_PRELOAD=/usr/lib/libc/memcpy-preload.so /usr/bin/iceweasel
$ LD_PRELOAD=/usr/lib/libc/memcpy-preload.so /usr/bin/chromium
You can find details about this in /usr/share/doc/libc6/README.Debian.gz and I
would suggest to create a little shell script like the following:
--- snip ---
#!/bin/sh
LD_PRELOAD=/usr/lib/libc/memcpy-preload.so /usr/bin/iceweasel
--- snip ---
and place is somewhere in your PATH (~/bin comes to mind) if that does indeed
solve the problem. Note that the path to memcpy-preload.so will change to a
multiarch conforming one in the next libc6 version that will hit wheezy. You
can then find it in /usr/lib/x86_64-linux-gnu/libc/memcpy-preload.so - but you
will be automatically informed about this is you have apt-listchanges
installed. If you don't install it and apt-listbugs with it. :)
I recommend reading the bug report on RedHat's bugtracker, it is worth your
time if you want to understand what is going on here.
