| Description: |
In unix/tclUnixChan.c, TcpGetOptionProc,
options -peername and -sockname.
if the size of the hostname returned by the system
causes Tcl to allocate memory for Tcl_DString 'ds',
that memory will never be freed.
I have tested this with:
while {1} {fconfigure $sock -peername}
hostname <= 195 chars - ok
hostname > 195 chars - memory leak
Patch included for Tcl-8.4.5
