consider the following piece of code, compiled with g++ 3.4

Just a question: why? G++ has one of the better library
implementations around, the STL port is one of the worst. So
why use it with g++?

std::stringstream ss;
int ii = 123;
ss << "test1";
std::cout<<ss.str()<<std::endl;
ss << ii << "test2";
std::cout << ss.str()<<std::endl;

The output I'm getting is quite strange:
test1
test1test2

It like 'ii' is not printed. If I remove line #4, then all is fine and
I get "test1123test2" also if to replace 'ii' in line 5 with some
string, like "test22", you'll get last line "test1test22test2" as
expected.

drives me crazy. any idea what it can be?

It would seem to be a bug in the STL. The above code works with
the default libraries with g++, Sun CC and VC++; I get the same
symptoms as you with Sun CC and the STL port, however.
