>Description:
I just noticed that, when I set the complaints level to
1 and try to debug C++ programs using std::strings, I get
the following message:

During symbol reading, const value length mismatch for '_ZNSs4nposE', got 8, expected 4.

In case you're curious, that symbol is:

std::basic_string<char, std::char_traits<char>, std::allocator<char> >::npos
>How-To-Repeat:
Create the following program:

#include <iostream>
#include <string>

int main()
{
  std::string s("foo");

  std::cout << s;

  return 0;
}

Then:

papaya$ g++ -g foo.cc
papaya$ /extra/gdb/mirror/src/gdb/gdb a.out
