Is it possible to backport this patch to 4.0.1?

I add below a ~100-line code. When compiling the code with
g++ -march=pentium4 -O3 -g -S allocator.cc
(g++ is version 3.4.2)
I get this assembly code:

One possible fix would be to look for common tail (and head?) sequences

You are violating C/C++ aliasing rules. Either use an union (which is defined
for GCC) or use -fno-
