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

Description:
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.
Test to reproduce the defect:

const size_t maxlen = 65536U;
char array[maxlen];

template

test_alloc(const test_alloc& rhs) throw() { }
template
test_alloc(const test_alloc& y) throw() { }
~test_alloc() throw() { }
size_type max_size() const throw() { return maxlen; }
};
int main()
{
typedef
std::basic_string > test_string;
int ret = 0;
size_t i, j;
for (i = 0; i < maxlen; i++)
array[i] = '*';
array[maxlen - 1] = '\0';
for (i = 0; i < maxlen - 1; i+= 8)
{
array[i] = '\0';
test_string s(array);
j = s.size();
array[i] = '-';
if (i != j)

std::cerr << "i = " << i << " j = " << j << " expected i == j"
<< std::endl;
ret = 1;
break;
}
