conky 1.3.4 gets glibc errors, most of the time double free errors, when you start it from a term in X, then ctrl+c kill it. reproducible on amd64 so far. Reproducible: Always Steps to Reproduce: 1. emerge conky 2. start /usr/bin/conky from a terminal in X 3. ctrl+c kill conky Actual Results: glibc errors, double free for myself and one other tester, invalid next size (normal) for one other tester so far. Expected Results: successfully die.

tested on ppc, glibc 2.3.5-r3 gcc 3.4.4-r1 works fine, no segv. seems isolated to amd64 so far on pre-gcc4.
Every person reporting problems here is running ~arch. I run +arch, so the problem must be with something masked. I will try with glibc >=2.3.5-r3 and see what I can turn up.
It would be helpful if people would post their conkyrcs here, or come to #conky on irc.freenode.net to help diagnose this.

weird issue this time, still a segv but a little different. weird thing is when you press ctrl+c it doesnt instantly kill now, it takes bout 5-10 seconds to die with the glibc error/s. details below: nathan@nathan1 ~ $ conky Conky: drawing to subwindow of root window (400004) Conky: drawing to single buffer Conky: received SIGINT or SIGTERM to terminate. bye! *** glibc detected *** double free or corruption (!prev): 0x000000000054b810 *** Aborted nathan@nathan1 ~ $ gdb conky GNU gdb 6.3 Copyright 2004 Free Software Foundation, Inc.

also with regards to: ok, thanks for testing. are you using the ${texeci} var any chance? that one runs a user defined script in a separate thread? ------------ im just using the default config, i dont actually have a conkyrc in either /etc or my home directory. pretty much just emerge conky then execute conky as non root. I might try copying in a default config in a sec, as ~/.conkyrc see what it does.
ok...interesting result. no segv when i kill it now. i just dropped a copy of the conkyrc.sample in as ~/.conkyrc and executed it, i still get the 5 or so second delay after ctrl+c till it dies, but it doesnt segv.
regarding the gdb session in comment #17: you need to tell gdb to pass SIGINT to the program. after you start gdb concky and get the (gdb) prompt, enter this command before you issue run: (gdb) handle SIGINT nostop noprint pass (gdb) run this tells gdb to pass the cntl-c to conky and will reveal more information. thanks.
also if there is someone kind enough to create a non-privileged account on an amd64 box showing the problem, one that will allow me to forward X packets over ssh back to my display, i might actually be able to get somewhere with this problem. i just need gdb, strace and the customary build tools.
hmm yea sorry my box is firewalled off at work, cant forward ssh through here. ill let you know if i find someone else that can.
can you do the following: delete your .conkyrc so we go back to the original situation in which you observed the sigsegv. make sure conky is compiled with -g and without -fomit-frame-pointer. I would like to see the output of these: 1) gdb conky (gdb) handle SIGINT nostop noprint pass (gdb) run <CNTL-C> 2) strace conky >strace-conky.log 2>&1 3) /lib/libc.so.6
forgot to mention, please: (gdb) bt after sigsegv when you hit CNTL-C. And please delete the previous patches and go back to 1.3.4. Please read previous comments. Thanks.

@ Daniel Black: The most recent ebuild and patch have been confirmed as a fix. It's been added to Conky CVS, however I'm probably not going to do another release just for this one bug fix. So, if you could please add this patch into portage with the 1.3.4-r1 ebuild, that would be greatly appreciated.
Created attachment 73545 [details, diff] app-admin/conky/conky-1.3.4-r1.ebuild.patch patch so the dev can see what changed with the 1.3.4-r1 ebuild.
Thanks Philip, Brenden and Nathan - will add shortly.
fixed - thanks Philip.
