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
