This bug has been triaged Martin, this back-trace is full of OCSP-related entries, and the signal appears to have happened after an attempt to decode. I can't find this as a duplicate and I'm passing this on to you. Let me know if we don't work on this, please. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
quickder.c comes from NSS land...
This looks like a recursive dependency between the responder certs from http://ocsp.usertrust.com and http://ocsp.comodoca.com We attempt to verify the signature on an OCSP response CERT_VerifyOCSPResponseSignature which calls into CERT_VerifyCert probably to verify the cert that produced the signature, but this verification triggers another call to CERT_CheckOCSPStatus then ocsp_GetOCSPStatusFromNetwork then again going to CERT_VerifyOCSPResponseSignature which causes us to repeat the same thing using the other cert. When having a big recursive stack, we eventually crash while trying to decode an OCSP response. Maybe we crash because of "stack overflow"? Do you know which web site triggered this crash?
Nathanael, which version of NSS did you have installed? rpm -q nss
I've reported the problem to upstream at https://bugzilla.mozilla.org/show_bug.cgi?id=551429

This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 WONTFIX if it remains open with a Fedora 'version' of '12'. 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 prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 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 please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. 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. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 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. Thank you for reporting this bug and we are sorry it could not be fixed.
