unsigned ui3 = ~((1 << 31) >> 3);
printf( "%x\n", ui3 );
give me wrong result fff ?

Do you mean this treatment: ~((1ULL << 63ULL) >> 3ULL) -> ~(1ULL << 60ULL) ->
efff ?

~((1ULL << 63ULL) >> 3ULL):
( 0001 << 63) -> 8000 (unsigned!)
(8000 >> 3 ) -> f000 (due to sign bit)
~(f000 )

Correct should be fff and fff.

__cxa_atexit and __cxa_finalize that work correctly
cxa.c contain code with __cxa_atexit and __cxa_finali
--- Comment #13 from hidden_peak at mail dot ru 2005-11-27 16:41 ---
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 plat

May be is not gcc bug, but ld: the sample work with GNU ld version 2.12.90.0.1
20020307 Debian/GNU Linux, work with warnings with GNU ld version 2.15.94.0.2.2
20041220 (SuSE Linux) and don't work with ld 2.16.x
--- Comment #12 from hidden_peak at mail dot ru 2005-10-06 11:28 ---
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

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

May be. Just for info: Debian GNU/Linux 3.0 ('woody'),
