Hello,

Badfully, I don't reproduce the pb with this file.
I made a rm -rf sal/unxlng* with the unchanged (so with GLIBCXX_DEBUG) 
files :
- sal/inc/unxgcc.mk
- sal/gbuild/platform/unxgcc.mk
and there's still the pb.


But when i use  the test file, nothing as you can see below :

$ g++ -D_GLIBCXX_DEBUG attachment.cxx
$ echo hello world | ./a.out
Line is: "hello world"

$ cat attachment.cxx
//compile with g++ -D_GLIBCXX_DEBUG
//see http://lists.apple.com/archives/cocoa-dev/2009/Sep/msg01096.html
//see

#include <iostream>
#include <string>

int main (int argc, char * const argv[])
{
    std::string line;
    std::getline(std::cin, line);
    std::cout << "Line is: \"" << line << "\"" << std::endl;
    return 0;
}
