Smaller testcase for the possible libstdc++ / C++ FE issue, build with
-O2 -finline-functions -Wstrict-aliasing -Wsystem-headers
#include <set>
class test
{
test();
void bar(int ci);
std::set<int> foo;
};
void test::bar(int ci )
{
test ctx;
ctx.foo.insert( ci );
}
/usr/include/c++/4.4/bits/stl_function.h: In member function void
test::bar(int):
/usr/include/c++/4.4/bits/stl_function.h:230: warning: dereferencing pointer
__x.13 does break strict-aliasing rules
/usr/include/c++/4.4/bits/stl_tree.h:530: note: initialized from here

I am now trying to investigate who is at fault.
