      Description

      From http://mail-archives.apache.org/mod_mbox/incubator-stdcxx-dev/200609.mbox/%3c451C1D61.1030807@roguewave.com%3e:

      This fails to compile without debugging iterators:

      #include <string>
      int main ()
      {
      std::string s;
      unsigned n = 3;

      s.insert (0, n, 'x');
      }

      $ make t
      gcc -c -I/build/sebor/dev/stdlib/include/ansi -D_RWSTD_USE_CONFIG -I/build/sebor/dev/stdlib/include -I/build/sebor/gcc-4.1.0-8s/include -I/build/sebor/dev/stdlib/examples/include -pedantic -nostdinc++ -O2 -W -Wall -Wcast-qual -Winline -Wshadow -Wwrite-strings -Wno-long-long t.cpp
      t.cpp: In function 'int main()':
      t.cpp:7: error: call of overloaded 'insert(int, unsigned int&, char)' is ambiguous
