APAR status

• Closed as program error.

Error description

• When using the provided Demangle function routine to demangle
  C++ names, the runtime appears to be leaking one byte per call.
  

Local fix

• N/A
  

Problem summary

• PROBLEM DESCRIPTION:
  A memory leak in the demangler interface may occur with certain
  input strings.  This is caused by heap allocations of one byte;
  which, in certain cases, are not reclaimed.
  
  USERS AFFECTED:
  Users of the demangler library in the C++ runtime or
  libdemangle.
  

Problem conclusion

• Did not use heap allocation for the case where the memory would
  not be explicitly freed.
  

Temporary fix
