Check his revision history and you should find it. He documents things well.

The rev history  here: https://www.eznec.com/Updates50.html

doesn't mention it.
There are a few issues with variable definitions in COMMON blocks (documented on W7AY's site), and the use of Intel Specific calls for command line arguments, etc. (not really bugs, more a "platform" issue, and a  problem with a constant not being double precision.

    In that retirement page, Roy mentions a known bug in NEC4.2. Does
    anyone
    have more information on that?

    "At the time of this writing, the compiled NEC-4.2 from LLNL has been
    found to contain at least one bug (which has been repaired in the
    current EZNEC Pro/4), and the recently released NEC-5 has a
    substantial
    number. There is currently no one at LLNL able to fix these and no
    one
    outside LLNL authorized to distribute updated versions, so anyone
    purchasing those programs and using them with the public domain EZNEC
    Pro program will encounter the bugs and may not have any way to
    get them
    fixed."
