Subject [jira] Created: (STDCXX-1035) Issue with string::find(const string& str, size_type pos=0)

Issue with string::find(const string& str, size_type pos=0)
-----------------------------------------------------------

                 Key: STDCXX-1035
                 URL: https://issues.apache.org/jira/browse/STDCXX-1035
             Project: C++ Standard Library
          Issue Type: Bug
          Components: 21. Strings
    Affects Versions: 4.2.1
         Environment: OS: Solaris 2.10
Compiler: Sun Studio 12
            Reporter: Brian Nesbitt


I recently encountered a problem with stdcxx demonstrated by the following example:

{noformat}
#include <string>

int main()
{
    std::string s = ".google.com";
    std::string s1 = "www.google.google.com";

    std::string::size_type pos = s1.find(s);
    if (pos != std::string::npos)
    {
        return 0;
    }
    else
    {
        return 1;
    }
}
{noformat} 

The code above was compiled using the sun studio 12 compiler:
{noformat}
CC -library=%none -I/spare/include/stdcxx -L/spare/lib -lstd12d -mt -lpthread google.cpp
{noformat}

With the stdcxx 4.2.1 library, the return code is 1 indicating that find failed. However the
return code is 0 when using sun studio with the Cstd or STLPort4 libraries. Compiling with
g++ 4.1 on Linux also returns 0 indicating that find was successful.
