------- Comment #4 from rguenth at gcc dot gnu dot org 2009-01-30 22:20 -------
Confirmed on i?86 as well, even with 4.3 headers:
./cc1plus -quiet -O2 -Wall /tmp/t.ii
t.C: In function 'void bar()':
t.C:16: warning: dereferencing pointer '<anonymous>' does break strict-aliasing
rules
/usr/include/c++/4.3/bits/stl_list.h:132: note: initialized from here
I will have a looksee.
