Summary:                    core dump when run against dot files from ruby 1.9
Description: 
dot segfaults on files in the ruby 1.9 source directory.  A backtrace is
below.  This may be related to the recent pixman update.

The call that produces the segfault is:
dot
/home/bwalton/opencsw/ruby19/trunk/work/solaris9-i386/build-isa-i386/ruby-1.9.2-p180/doc/capi/html/d8/d18/ruby_2ruby_8h__dep__incl.dot
-Tpng -o ~/dot.png

I'll attach that dot file for reference.

Observed similar issue, can be reproduced with the minimized dot file
snipped that's pasted below. Tested with bmp and png as output formats.
Both segfault, but only on Solaris 9, not on Solaris 10.

$ uname -a
SunOS unstable9s 5.9 Generic_Virtual sun4u sparc
SUNW,SPARC-Enterprise-T5220

$ cat crash.dot
digraph g {
    "foo" -> "bar";
}

$ dot -Tpng -o crash.png crash.dot
Segmentation Fault (core dumped)
