Sorry, problem solved using a complete set of SGI STL 3.3 and then putting yours on top.

Cheers

John

With some further testing I am finding a problem which I also found with SGI STL 3.20 previously.

Consider the following function returning a string:

string Name(string a) {
    return a;
}

The conditional code assignment fails when the boolean value is false:
    bool test;
    string a = "a";
    test = false;
    // This fails for false and returns garbage in the string.
    string s = test ? "true" : Name(a).c_str();
    // This works for false.
    string s2 = test ? Name(a).c_str() : Name(a).c_str();
    // This works
    s = test ? string("true") : Name(a);
    // This works
    string t = test ? "true" : a.c_str    // This works
    string u;
    if (test) u = "true"; else u = Name(a).c_str();

I also need to define this to get termination of the strings:

#define __STL_DEFAULT_CONSTRUCTOR_BUG

Cheers

John

Correction, the previous line should be:
string t = test ? "true" : a.c_str();
// This works

I had better append a complete program file.

Oops. The files with no extension didn't make it into the zip file. I fixed it, try downloading it again.

I'd like a (small) test case demonstrating this is needed. Thanks!

I'll try again with your latest distribution.  If there is still a problem I'll do an example.

Here is a small case which gives different output with and without the define. The outputs I get are in a comment in the program.  Compilation in the directory with the SGI 3.3 is   sc -I. onestr.cpp.

John

thanks!
