fatal error using mm .S macro to double-space (.S 12 24)

[jimav]

Binary package hint: groff

Increasing the vertical spacing (e.g. for double-spaced text) using the -mm .S macro causes an internal error if there is too much text in a paragraph. For example, .S 12 24 should format text in 12-point font with 24 point vertical baseline separation. It works unless a paragraph is too big.

Attached is a demo file. To see the problem:

  groff -mm -Tps (attached file) >/dev/null
  fatal error: input stack limit exceeded (probable infinite loop)

Using groff in Ubuntu 8.10
groff --version
GNU groff version 1.18.1

I've confirmed this to be fixed in groff 1.20, which I hope to upload to Debian unstable and thence to Ubuntu karmic over the next couple of weeks.

I uploaded groff 1.20.1 to Debian unstable yesterday, and just synced it into Karmic.
