| Summary | 0001790: segfault on startup with Unreal 3.2 final | ||||
| Description | could this be related to any of the modules I have loaded? I removed the include for spamfilter.conf and the segfault still happens on startup. | ||||

I found what was causing this ;) When I compiled Unreal 3.2 on this box, it had OpenSSL 0.9.7c on it.. A short time afterwards, OpenSSL was upgraded to 0.9.7d on the box. This was causing curl to fail, and the ircd to segfault when I tried to start it.. So basically what this means is (correct me if I'm wrong), anyone using Unreal 3.2 with remote includes cannot upgrade their OpenSSL version unless they also re-compile Unreal and curl, otherwise the ircd will segfault the next time its restarted. Without curl and remote includes, Unreal can restart with no problems at all, even if the OpenSSL version installed doesn't match the version that was in use during compilation. I hope somebody has a way around this problem with curl (besides using curl without ssl), because if an important update for OpenSSL is released in the future, I doubt if everybody wants to re-compile unreal and curl just because of that :( |

Anyway i don't think that is SOOO difficult to recompile unreal.. |

No it's not difficult, but that's not the point. If someone who is running unreal with curl+ssl has to upgrade OpenSSL for whatever reason (some vulnerability is discovered etc), and then a while later their box is rebooted, or if their ircd needs to be restarted for some other reason, the ircd will segfault on startup and they won't know why (unless they read this). I'm probably just going to use curl without ssl support for now, that way this won't become a problem for other servers on the network. |

heh I'm not surprised, openssl has been giving me weird kind of issues too in the past... They also don't seem to care much about it, here's an excerpt from 'INSTALL': Note on shared libraries ------------------------ Shared library is currently an experimental feature. The only reason to have them would be to conserve memory on systems where several program are using OpenSSL. Binary backward compatibility can't be guaranteed before OpenSSL version 1.0. |

I guess this can be closed then :p. |
