Octave structs are not associative arrays. Part of their
implementation detail is that C++'s std::map is used to implement
them, and this is casually mentioned in the manual. SS has latched on
to this statement and concluded Octave is like Perl, or it's buggy
because it's not like Perl.

Octave's structs are supposed to look a lot more like C structs than
like Python dictionaries or Perl hashes or PHP arrays.

The fieldnames in a struct are subject to the same constraints that
variable names are. In essence, they have to start with a letter, no
spaces, and may only contain letters, numbers, and underscores.
