Re: [Bug Report] Inquiring about GNU gawk-5.1.0 program bug report

[arnold]

Hello.

The crash is not related to the value supplied to the -F option, but
rather to the --nos, which is short for the undocumented --nostalgia
option that purposely printed an unhelpful message and aborted.  That was
an Easter Egg.

The --nostlagia option has since been removed. The current version of
gawk is 5.3.1.
