COMMENTS:
PJ28372 addresses a memory leakage issue with the iconv_open() api.
Iconv_open() will malloc
a "iconv_t" structure which it uses for
iconv() api processing.  Inside this structure iconv_open() will malloc
three more members.  Iconv_close() releases the memory for the structure
but not the members.  Hence, any application using ICONV processing will
have a small memory leak for every call.  However, this
leak can grow
to significant sizes when dealing with long life ECBs.


SOLUTION:
PJ28372 solves the memory leak issue in ICONV processing by simply
freeing the members of the structure
within the iconv_close() api.
