fvwm repeatedly crashing

If it doesn't seem to have anything to do with FVWM directly it should be asked here.

fvwm repeatedly crashing

Postby bobl33 » Tue Feb 16, 2016 12:14 am

Configuration Information [Automatically generated, do not change]:
uname: Linux jdiamond-nb2 4.1.2 #1 SMP PREEMPT Fri Jul 17 18:16:03 ADT 2015 x86_64 Intel(R) Core(TM) i7 CPU M 620 @ 2.67GHz GenuineIntel GNU/Linux
compiler flags: gcc -Wall -Wno-implicit-int -O2 -fPIC

FVWM Version: 2.6.5
FVWM_MODULEDIR: /usr/libexec/fvwm/2.6.5
FVWM_DATADIR: /usr/share/fvwm
FVWM_USERDIR: /home/zsd/.fvwm

Description:
fvwm occasionally crashes (a few times a day).

Repeat-By:
Since I've started trying to take note of when it crashes,
every time it was when I was switching tabs in firefox,
opening a new tab or closing a tab (I'm currently running ffx
38.6.0esr but this crashing problem has been occurring on and
off for quite a while, so it is not specific to that
particular version of ffx). However, I'm not certain that
changing tabs in firefox is the only time it happens.

FWIW:
(1) I'm using Slackware64-14.1 on a Fujitsu T900 with a Core i7
M620, 8 GB of ram.
(2) I've let memtest86 churn away for a long time with no reported
problems. No other program on my system is showing any problems,
so while I'm not certain that it isn't a bad hardware problem, I
don't see any evidence of that either.

I saved a couple of core dumps. If further information from those
would be of use let me know.

Any ideas? Thanks.

Hi,

please post your report on the FVWM workers mailinglist because it's too specific for the forums. How to do this see here.

Thanks,

Thanks. But...

I actually tried that first, and while I never got a bounce to my e-mail message, my message doesn't show up when I visit the archives to which that page links:
http://www.mail-archive.com/fvwm-worker ... llist.html
Further, when I get that web page to sort by date, the most recent date it lists for me is
2015/06/18 Re: Fvwm commit problem ...
so I was beginning to think the mailing list was defunct.

At the risk of adding to the topic here, is that archive current? I guess I can send e-mail to the list owner, which I will do now.

Have you sent an email with "subscribe" in the body to fvwm-workers-request@fvwm.org?
Also it is important that you've send it as a pure text email - no html header shall included anywhere in the mail. For example my German provider web.de do this, whether I've set it to text :? Therefore I have to use a client for my web.de account or another provider which send true text emails (e.g. Google).
And last but not least only those email address from where you've sent the subscribe mail is valid after you've got an activasion email.

No it is working but ...

... the update cycle is longer than on other mailinglists, I'm afraid :(

Not until a minute ago. http://fvwm.org/contact/ doesn't mention that you must be a member of fvwm-workers to e-mail to it, nor does the man page for fvwm-bug, so thanks for mentioning that.

I'll try e-mailing the bug report (in plain text!) in a few minutes. I'm not sure whether I should expect a "you're in" response to the subscribe request, but if nothing shows up in a while I'll cross my fingers and e-mail the report.
