Point taken - I'm going back to GCC 4.2.4 which has never caused any problems
for me.

BTW, I'm not using any extreme GCC flags, for the last few years I compile all
sources either with:

C   Compiler flags: -march=pentium2 -O2 -pipe -ftree-vectorize
C++ Compiler flags: -march=pentium2 -O2 -pipe -ftree-vectorize
Linker flags: -Wl,-O1 -Wl,--hash-style=gnu -Wl,--enable-new-dtags

or with:

C   Compiler flags: -march=native -O2 -pipe -ftree-vectorize
C++ Compiler flags: -march=native -O2 -pipe -ftree-vectorize
Linker flags: -Wl,-O1 -Wl,--hash-style=gnu -Wl,--enable-new-dtags

Anyway, it looks like GCC is kinda degrading because these innocuous flags
cause some much stir, however Linux kernel works nicely having compiled with
the aforementioned flags (albeit without -ftree-vectorize).
