Description of problem: With the attached file: $ neato -Tpng dependencies.dot > dependencies.png out of memory Segmentation fault (core dumped) Version-Release number of selected component (if applicable): graphviz-2.34.0-10.fc20.x86_64 How reproducible: 100%
Created attachment 998505 [details] another crasher Another one: $ dot -Tx11 dependencies2000.dot segmentation fault (core dumped)
Same problem on f21, changing version to f21 and reporting upstream.
But the following works: $ neato -Tpng dependencies2000.dot dependencies2000.png machine with 8 GB RAM.

It seems it runs out of stack space during recursion.
Probably 8 MB stack isn't enough for recursion in such huge task. With 'setlimit -s unlimited' it runs, runs and runs. Currently I am not sure whether it is doing useful work or just simply cycling. I will let it run for a while and let's see. The limits and aborts are glibc business. I don't know whether we can easily treat this (without performance penalty), i.e. check whether the task requires more resources than available and correctly exit.
This message is a reminder that Fedora 21 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 21. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '21'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 21 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 21 changed to end-of-life (EOL) status on 2015-12-01. Fedora 21 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
