This is really bug in glibc: __cxa_finalize don't call all registered handlers
in case of NULL argument (glibc 2.2.5 has this bug, but 2.3.2 already not).
But nevertheless, the problem still present at platforms withou

Really, I wonder why code specific for C++ language support should be in glibc?
What about platforms without glibc? May be code to call dtors should be in
crtbegin/crtbeginS?

Sometimes test run fine fror me too, but (the same build and same evironment!)
sometimes not. This like depends upon garbage... Well, as expected---call of

And how I configured GCC:
earth:~>~/ia32_linux_gcc3_4/bin/gcc -v
Reading specs from
/home/gates/pinskia/ia32_linux_gcc3_4/lib/gcc/i686-pc-linux-gnu/3.4.0/specs
Configured with: ../configure --prefix=/home/gates/pinsk

Here is the output I have for those files in 3.4.0:
earth:~>nm ~/ia32_linux_gcc3_4/lib/gcc/i686-pc-linux-gnu/3.4.0/crtendS.o

But may be this is problem in crtbeginS.o or crtendS.o? I.e. in something like
__cxa_finalize:

This sounds like a bug in your glibc then.

It works with your script too:
sh -x x.sh
+ CXX=/home/peshtigo/pinskia/ia32_linux_gcc3_4/bin/c++
+ /home/peshtigo/pinskia/ia32_linux_gcc3_4/bin/c++ -pthread -fexceptions
-fident -g -fuse-cxa-atexit -c -o test.o test.

This works for me with:
