APAR status

• Closed as program error.

Error description

• The compiler does not properly encode certain names in the "std"
  namespace.
  
  Instead of mangling "std" into a mangled name, or
  using the demangled names with "std::" qualification, it uses an
  "std__" prefix on the name as in the example below:
  
  
  d1.<> dwhat m1
  In thread 1.1:
  Name: m1; Type: class map<int,int,std__less<int>,
  std__allocator<std__pair<const int,int> > >; Size: 24 bytes;
  ...
  ...
  
  The names "std__less", "std__allocator", and "std__pair" should
  instead be "std::less", etc.
  

Local fix

• N/A
