There is nowhere wording that passing NULL is valid. Your code is simply buggy.
Fix it instead of complaining about other people's code.

Do not shoot the messenger.
the problem can easly be fixed.
i will send a patch (to the documentation) to warn about the use of NULL as
optstring.

No need to send a patch for the documentation. This is never documented and we
won't start because with the same argument we would have to say, for every
string function for instance, that passing a NULL pointer will cause a crash.

Subject: Re: getopt_long() crashes if optstring is NULL
this is ok for string functions. but sometimes getopt_long() may get
optstring==NULL because some user has a program without any short option.

It's exactly the same issue. If a function expects a string passing anything
else is undefined behavior and will likely lead to crashes.
