Have a great day ahead!

Because of what I said in my original reply:

Hi,
Thank you so much for your time and reply.
We understand that the entire point of `xrealloc` is never returning 0 to
client users/developers who use this function. However, the issue we
reported here happens when the `xrealloc` internally handles the returned 0
from `realloc` or `malloc`
