Can you attach the actual dot file causing the problem? Thanks.

File is too large to upload directly; see here:

$ gc redacted.dot
   88488 146642 structs (redacted.dot)
$

I think 88488^2 * sizeof(double) * 3 (I think the solver needs 3 NXN matrices)
gets to about 350 gigs of RAM.

Not sure if we should have been able to catch this and emit an error.

I respect that my dot file was too large, but segfaults are never graceful. :)

I'll try reducing my dataset and leave it up to you what the best action should be for this report.

Thanks for the quick turnaround!

Cheers,

Jesse
