[Wien] ERROR: negative position

[Kateryna Foyevtsova]

Dear Gavin,

I am also getting this message

ERROR: negative position in rstruc. Please report

for the structure I append below.

Could you give a hint what is the problem and what should I fix to get
rid of it? I am using version 12.1.

Thanks!
