The problem comes with a command like PUT PURSE OF GOLD ON TABLE.
The parser (parserm.h line 1696) has a comment "Advance past the last preposition".
It does this in order to parse second=table, so that it can handle the multiexcept token correctly. Good in theory, but it actually advances to the word "OF".
Which is a preposition because of the grammar line "lie on top of noun".
(And I believe we're adding "get off of noun".) It then accepts "gold on table"
as the second noun token, and pops a disambiguation question -- even
though "of" is not a valid preposition for "put X on Y". The parser tests "(l->#dict_par1) &8", examining the preposition flag in
the dictionary. It would be better if it instead searched for the specific
preposition(s) in the grammar line it's testing. (See L61127.)
