|Summary||0000173: Windows core dump using -Gpack with neato|
that the feature -Gpack has been added to the new release of GraphViz.
Gpack is a great feature, I really enjoy the more compact layout that it
produces. However, I found from time to time by using -Gpack, neato reports
error (I'm using Windows XP Pro):
"neato.exe has encountered a problem and needs to close. We are sorry for
the inconvenience. ..."
Attached please find a sample file that incurred such problem. BTW, I was
calling neato in a Perl script, and the system call was:
neato -Gpack -Gmaxiter=50000 -Tsvg path$time.txt -o core_network$time.tmp
I found that by using a much larger -Gepsilon, say -Gepsilon=16, the error
can be avoided. However, the layout is somewhat ugly.
[erg] The error appears to be an access violation. The -Gpack flag is necessary,
but any single additional -G flag causes the problem. Also, I could replicate
this on mswindows, but not on a different machine.
The problem appears related to the number of subgraphs. Removing even one
of the anonymous subgraphs fixes the problem. More generally, a workaround
would be to not use anonymous subgraphs to attach attributes, but attach
the attributes directly to the nodes.
