3593.0. "Missing symbol CXX$NPS55BSCSTRNGC22STRN0NK0DNJ" by CSC32::EHA (Flip) Fri May 30 1997 15:33

    Hello,
    
    I have reproduced a problem that a customer sent in on an Alpha VMS 6.2
    using DEC C++ V5.5-017.  The following log file show what I have done:
    
$ ver = f$verify(1)
$ on warning then goto clean_up
$ create test.cxx
// Test.cxx

#include <iostream.h>
#include <algorithm>
#include <assert.h>
#include <vector>

vector<char> vec(char* s)
{
  vector<char> x;
   while(*s != '\0')
      x.push_back (*s++);
   return x;
}

main()
{
  cout << "Using reverse algorithm with a vector" << endl;
  vector<char> vector1 = vec("Mark Twain");
  reverse(vector1.begin(), vector1.end());
  assert(vector1 == vec("niawT kraM"));

}

    Do you have any idea where this is comming from?

We've reproduced the problem ... there is an unresolved
external reference in one of the standard library
object files to basic_string<char>::npos. We're
investigating a solution...

We've rebuilt a libcxxstd.olb for V5.5 that fixes this problem and are working
on the details of getting it to the customer.
