Fatal Error: Illegal Object

I encounter an illegal object error in the game balances.z5 (https://ifdb.tads.org/viewgame?id=x6ne0bbd2oqm6h3a), when using Dumb/Normal Frotz. To replicate, simply load the game and type "take her" as your first action.

Invoking Frotz with the -i argument to avoid fatal errors results in a segfault.

Broadly, I'm curious if the issue introduced by a bug in the game itself? Or by Frotz's interpretation of it?

Until quite recently, someone lived here, you feel sure. Now the furniture is matchwood and the windows are glassless. Outside, it is a warm, sunny day, and grasslands extend to the low hills on the horizon.

You can't see "her" (@Attempt to address illegal object -1.  This is normally fatal.
