APAR status

• Closed as program error.

Error description

• When -qheapdebug is used, the above test case gives out error
  message about "std::_debug_malloc" not declared.
  
  $cat xlc12_defect_heapdebug_stdnamespace.cpp
  #include <cstdlib>
  
  signed main(void) {
    void * buf = std::malloc(1U);
    return EXIT_SUCCESS;
  }
  
  $xlC_r -qheapdebug -o xlc12_defect_heapdebug_stdnamespace
  xlc12_defect_heapdebug_stdnamespace.cpp
  
  "xlc12_defect_heapdebug_stdnamespace.cpp", line 4.16: 1540-0130
  (S) "std::_debug_malloc" is not declared.
  

Local fix

• Modify the header /usr/vacpp/include/cstdlib and put the
  offending memory functions under the std namespace.
  

Problem summary

• PROBLEM DESCRIPTION: Heapdebug entry points are not defined in
  the STD namespace.  It gets an error message about std::malloc
  not declared.
  
  USERS AFFECTED: Users who use std::malloc() and have
  -qheapdebug option specified.
  

Problem conclusion

• The compiler header is fixed. Apply applicable service.
