Hi.
I discovered the following problem using boost::tokenizer. The
following program should print "hello", but it prints "hell":
#include <iostream>
#include
int main(){
typedef boost::tokenizer tokenizer;
boost::char_separator<char> sep(",", "");
tokenizer values(std::string(",hello,"), sep);
for( tokenizer::iterator valueI = values.begin();
valueI != values.end();
++valueI){
std::cout << "\"" << *valueI << "\"" << std::endl;
}
}
Problem is confirmed using boost 1.32.0 and both
GCC 3.3.4 and GCC 3.3.5
If anybody have a newer GCC installed, I would like to hear if the
problems also exists in later GCC releases.
I believe it is a bug in the std::string::assign implementation
(i.e. not boost directly), but a the workaround for msvc in
boost/token_functions.hpp, line 215-228 has also been tried for the
GCC but it just moves the problem; it will mibehave when the line
tokenizer values(std::string(",hello,"), sep); is replaced with
tokenizer values(std::string("hello,"), sep); since it will then print
"hel". So maybe another boost workaround is needed for GCC for the
lines 215-228 in boost/token_functions.hpp
