SEGV fault when using wchar_t streams

["Rob Lugt" <roblugt at bigfoot dot com>]

Using gcc 2.95.2 and libstdc++ snapshot 2.90.8

 

I compile the following program with ./g++ -fhonor-std

 

      1 #include <iostream>
      2 int main(int argc, char* argv[])
      3 {
      4     std::wcout << L"H";
      5     std::wcout << L'i' << std::ends << std::endl;    // This appears to be the problem line
      6     std::wcout << L"This is going to die - bye" << std::endl;
      7 }

 

If I run the resulting program I get the following output:-

 

Hi
This is going to die - bye
Segmentation fault (core dumped)

 

If I comment out line 5 the problem goes away.  It seems the problem is related to the outputting of a wchar_t to a wchar_t stream.  I get the same error if I create a wofstream. 

 

The problem does not occur until program termination.
