Summary: snmpget potential memory leakage

Initial Comment:
At moment I use version 5.1.1 (but what I report appear
to be valid in 5.2pre3 too). I was suspecting a memory
leakage in some of snmpget components and I made a
trivial modification in snmpget.c (see attached code),
in order to iterate snmpget funcionality and trying to
expose any potential leakage. Maybe I'm doing wrong but
what I see from 'top' or /proc process information is a
growing memory usage. In particular these are the
ever-growing figures:VmSize:     

6312 kBVmRSS:      
2160 kBVmData:      
736 kB

Note that this test makes correct requests to the agent
(valid oid) and returned values are consistent.

I understand this could be a no-problem for a command
line tools like snmpget, but it is critical in my
project since I do provide snmpget functionalities
through a library function. What reported appear to be
present in both Linux and Win32 builds.

I'm not an expert in using debugging and profiling
tools, so any help will be appreciated to understand
(and possibly solve) this problem. I'd like to help in
tracking this thing down, if possible. Since I can't
state where the leakage is (if it is really so...) I'm
possibly reporting an already known problem: please
forgive me if so. ;-)

Modified snmpget.c follows:
--
int
main(int argc, char *argv[]) {        
  while(1) {                
    _main(argc, argv);        
  }
}

int
_main(int argc, char *argv[]) {
  <unmodified original main()>
}
