Should that not be

  .ie \\n(.tu<=1i ...

since the value stored in the .t register is not inches, but a measure
in troff units?

Also, IIRC, when you place a comment after \{, you need to write it as

  \{.\" comment text

(note the dot), otherwise you get an unwanted significant line break in
the input stream.

Similarly, .p is a measure in troff units.  When you multiply these,
possibly quite large .t and .i values by 72000 units per inch, the huge
result will very likely cause the overflow you report.
