Subject [jira] [Created] (STDCXX-1057) attempting to create a std::string of size 65535 or greater fails with Perennial CPPVS V8.1

attempting to create a std::string of size 65535 or greater fails with Perennial CPPVS V8.1
-------------------------------------------------------------------------------------------

                 Key: STDCXX-1057
                 URL: https://issues.apache.org/jira/browse/STDCXX-1057
             Project: C++ Standard Library
          Issue Type: Bug
          Components: 21. Strings
    Affects Versions: 4.2.1, 4.2.x, 4.3.x, 5.0.0
         Environment: Solaris 10 and 11, RedHat Linux, OpenSuSE Linux
SUN C++ Compilers 12.1, 12.2, 12.3
Defect is independent of compiler and platform
            Reporter: Stefan Teleman
             Fix For: 4.2.x, 4.3.x, 5.0.0


in member function:

size_type basic_string<_CharT, _Traits, _Allocator>::max_size();

the maximum size of a basic_string is restricted to less than 65535 bytes.
The Standard is ambiguous as to what the max_size() of a std::string should
actually be (see LWG Core Issue 197). However, less than 65535 bytes for
the max_size of a std::string is rather small. GNU libstdc++ and stlport4
set std::string::max_size to (SIZE_MAX / 4) (i.e. 1GB). Solaris sets it
to SIZE_MAX.

Perennial CPPVS explicitly tests for the creation of a std::string of size
greater than 65535. In the current stdcxx implementation, this test fails.

The max_size of a std::string should be significantly greater than 65535 bytes.

Patch for 4.2.1 to follow shortly.
