Memory Corruption Crash in libyang

[pnayek8470]

Issue Details: While running with approximately 100 ONTs and periodically querying PON counter statistics, a crash occurs in libyang. This appears to be a memory corruption issue, as it is intermittent. Debug statements indicate an invalid memory address (0x1) is accessed during a free() operation. stack.txt

I have briefly looked at the relevant code and found nothing suspicious so I am afraid I will not be able to help without reproducing the issue. However, since you are using a 2 year old version of libyang and the other projects, it is also likely the issue has been fixed in the meantime so my first advice is to update to the latest releases.
