Running graph-tool "2.23dev (commit b626e713, Tue Mar 28 22:29:08 2017
+0100)", compiled using GCC 5.4.0 on Ubuntu 16.04 I get a "Segmentation
fault (core dumped)" error when running the following:
import graph_tool.all as gt
g = gt.collection.data["dolphins"]
This issue does not seem to arise for me when running version "2.22 (commit
44bf2b92, Thu Mar 2 23:08:39 2017 +0000)" (i.e. the latest apt-get release).
Is this an issue caused in the dev version of graph-tool or is this caused
by me compiling something incorrectly? Can anybody reproduce this error?
Unfortunately there is no backtrace whatsoever. All I get is Python
terminating (if I run it interactively) and the message I posted being
displayed. Nothing else appears on my screen.
I am able to use it on my other computer using version "2.23dev (commit
316f8a3d, Tue Mar 28 14:07:46 2017 +0100)" so this issue is by no means
critical to me if you have other things to get on with.

You have to get a backtrace using GDB; it does not happen automatically. You
can google "gdb backtrace" to see how it is done.

I most certainly have other things to do; but it is up to you if you want to
provide the backtrace to investigate further.

It looks like it (though it is funny that the other computer using the same
package version doesn't have the issue). It has been a major battle to get
all the dependencies to work in Anaconda python so seeing as I have a
configuration that currently works I am inclined to stick with the versions
I have for now unless other issues also start cropping up. Being able to
compile new versions of graph-tool easily is more important to me I think.
Thank you for looking into it though!
