"formatting message" backtrace_rating: 4 Package: evolution-3.4.3-2.fc17 OS Release: Fedora release 17 (Beefy Miracle) Thanks for a bug report. I do not see from it what can be wrong, evolution only failed to allocate 2KB of memory, while it was formatting a message with inline pgp signature (or encryption, I cannot tell for sure from the snippet I see in the backtrace). I tried to create an inline GPG signature, but it works fine for me if I import it into evolution - maybe it's too short? My question is, can you reproduce this with that particular message, please?

test email
This test email works fine for me.
Thanks Milan - it appears to happen "at random" while reading mails - I assume every time I hit one that has the "problem" formatting. I think the failure is more than just an allocation problem however - the process takes a sig11 during malloc which generally indicates arena corruption. Maybe there's a problem in an error path? Anyway; thanks for your analysis so far - I'd wondered if there was a link to pgp signed messages from the backtrace data. I will see if I can get it to trigger any more reliably with this information. You are right, this kind of crashes usually mean memory corruption. I wanted to get a reproducer first, then involve valgrind, because it's easier to know steps to reproduce than to run evolution under valgrind for an extended period (evolution is very slow when under valgrind). You can run evolution under valgrind with command like this:
$ G_SLICE=always-malloc valgrind --num-callers=50 evolution &>log.txt
but before that edit /usr/lib64/valgrind/default.supp and add there these 5 lines at the top:
{
Skip any wcslen calls
Memcheck:Addr8
fun:wcslen
}
to avoid false-positives which are triggered with wcslen usage in F17. The log.txt may contain some useful information, even if evolution will not crash, because valgrind can avoid certain crashes.
This message is a reminder that Fedora 17 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 17. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '17'. 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 17'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 17 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 17'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 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 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. |
