Betreff: optimization -O2 broken?

I'm the ArchLinux package maintainer for tzdata. We are using gcc
4.3.2/glibc2.8- We have run into a small problem with compiler

Using our default CFLAGS="-march=i686 -mtune=generic -O2 -pipe" the
zdump binary is built in broken way on i686 architecture. I have to
apply -O1 to make zdump work. See our bugreport:

I could confirm this when running zdump -v EUROPE/BERLIN it stuck after
two printing first two lines.

x86_64 architecture doesn't seem to be affected. Any idea why this
happens and how to fix it?
