A try to get rid of spam reports about "vulnerabilities" that are not real.

 No need to check integer overflow since that is 2*16*count = 2^32-1 ; => count = 128 M entries,
 That would be 2Gb, which is over MAX_MEMORY_FOR_ALLOC, even for large file size.
 I added this check to silence the continuous spam reports of people using AI to catch what
 they think are "vulnerabilities".
