Can you please send us the core of the crashed application? It should be in $HOME/.cache/abrt/ccpp-<something> Created attachment 702824 [details]
Entire directory of ccpp from arbt
~/.cache/abrt/spool/ccpp-2013-02-26-04:02:21-1855/
Thank you for the effort, but unfortunately that archive is empty, can you please re-pack it and re-upload it? Created attachment 703758 [details]
Entire directory of ccpp from arbt

The coredump is truncated. I'm attaching it separately. Created attachment 794671 [details]
Truncated coredump
ELF utilities balk on it in various ways:
$ objdump -drsx coredump
objdump: coredump: File truncated
$ eu-unstrip --core=coredump -n
eu-unstrip: No modules recognized in core file
$ readelf -aW coredump >OUT
readelf: Error: Unable to read in 0x8398 bytes of notes
I propose that we file a kernel bug "allow coredump helper to know when kernel truncates the coredump". Currently, kernel sends coredump data to the helper over a pipe. Pipes (so far) have no facility to report errors from writer to reader: writer can only close the fd, resulting in EOF on reader's side. What we want here is to get a -ESOMEERROR on reader side when kernel discovers that it can't finish the coredump correctly - and there *are* cases when that happens. This message is a reminder that Fedora 18 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 18. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '18'. 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 18's end of life. Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 18 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 to Fedora 18's end of life. 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 18 changed to end-of-life (EOL) status on 2014-01-14. Fedora 18 is no longer maintained, which means that it will not receive any further security or bug fix updates.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. |
