Package: python-graph Version: 1.8.2-4 Usertags: goto-cc During a rebuild of all Debian packages in a clean sid chroot (using cowbuilder and pbuilder) the build failed with the following error.
[...] test_topological_sort_on_very_deep_graph (unittests-sorting.test_topological_sorting) ... Segmentation fault Makefile:69: recipe for target 'test' failed make[2]: *** [test] Error 139 make[2]: Leaving directory '/srv/jenkins-slave/workspace/sid-goto-cc-python-graph/python-graph-1.8.2' debian/rules:20: recipe for target 'override_dh_auto_test' failed make[1]: *** [override_dh_auto_test] Error 2 (The full build log is attached.) Upon inspection via gdb it becomes apparent that this is caused by excessive recursion, which eventually causes a stack overflow. This is due to the following lines: http://sources.debian.net/src/python-graph/1.8.2-4/tests/unittests-sorting.py?hl=82,83#L82 Changing the numbers to 16876 and 16875, respectively, was the maximum I got to work. I'm leaving the severity untouched as (a) this is a test case only and (b) really the underlying code should be reconsidered to turn recursion into a loop - after all the present number of nodes doesn't seem terribly large. Best, Michael
