Pic macro arguments causes core dump.

[Greger Asplund]

Hello, group!

Is there a limit to the number of arguments a pic macro can take?
I wrote a macro with ten arguments, which led to a core dump on my 
system (OpenBSD 3.0, pic ver. 1.15).

An example:

# file.pic begins
..PS
scale = 10
define big_macro {
        line $1
        box wid $2
        line $3
        circle diam $4
        line $5
        ellipse ht $6 wid $7
        line $8
        box ht $9
        line $10
}

big_macro(1,2,3,4,5,6,7,8,9,10)
..PE
# file.pic ends

Now; when processing this:

$ pic file.pic
..lf 1 file.pic
..lf 1
Memory fault (core dumped)


With the call
big_macro(1,2,3,4,5,6,7,8,9)
it works.  Two digits is obviously too much for it to handle!

Why is this?
