[Bug c++/40391] New: Segfault with -O, iostream, anonymous namespace on PPC

[fp at mc dot com]

When compiling the attached code with gcc 4.2.1 with -O, the result fails on
PPC linux:

host> ppc86xx-linux-c++ -O -g -o iostest iostest.cxx
target> ./iostest
Segmentation fault

The code works fine:
- When built without optimization
- On x86 linux (also using gcc 4.2.1)
- With #define WORKAROUND (to avoid using an anonymous namespace)
