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?
