[libsmi] memory leaks in smi 0.4.8

28 Feb 2011


      ...
I have detected a couple of memory leaks (using Visual Leak Detector) in a
project where I parse a MIB with 4 imported MIBs.
One (44 bytes) seems to be associated with 'parser.pendingNodePtr'
allocated 
 in smiInitData. (adding smiFree(parser.pendingNodePtr); at the end of the
function removes this leak).
The 2nd leak (36 bytes) originates in smiLoadModule used to handle the MIB
parsing. The call stack returned was:
  Call Stack:
    c:\projects\hf sdr\msvc\smi-0.4.8<stdout> (14160): smirealloc
    c:\projects\hf sdr\msvc\smi-0.4.8<stdout> (13871):

Any insights welcome.
