It's a bug.

ps.map feeds the labels directly into the PostScript file unaltered.

If you want to use unmatched () or spanning two lines you need to
have the label as "\(", "\)"
You can edit the .ps file after to do this.

ps.map should really do this for you, but currently it doesn't.


e.g. from a .ps file:
(34) 180.919200 669.694805 MS
(Helvetica-Bold) FN 13.0 SF
(Regional map showing interpolated values for February)


If you have an unmatched ")" in the label, the .ps interpreter will
think it is the end of the text string and the rest is PS commands..
& then crash.
