lasers commented 6 years ago

Can you still reproduce this? And do you have a new syntax conky.conf?

progserega commented 6 years ago

I convert to new syntax: https://pastebin.com/pLpyCms0 Now conky work more stable. But time to time it is sigfault. I will try send backtrace when it is down.

lasers commented 6 years ago

Run (gdb) bt full instead of (gdb) bt. Thanks. Are you still on 1.10.1-3 ?

@lasers same malloc.c file that doesn't exists anymore in the current master branch.

conky: malloc.c:3722: _int_malloc: Assertion `(unsigned long) (size) >= (unsigned long) (nb)' failed.

@progserega can you test the current master branch ?

git clone https://github.com/brndnmtthws/conky
cd conky
mkdir -p build
cd build
cmake ../
make -j4

@su8 Duplicate https://github.com/brndnmtthws/conky/issues/77? He have teh mpd variables too.

@progserega Do what @su8 asked. Test it again on 1.10.8 or preferably 1.10.9_pre (git). The older versions are not trustworthy due to too many changes which can be hard to track. Thank you.

su8 commented 6 years ago

@lasers #77 is different, as lua failed there.

progserega commented 6 years ago

Hmm... ubuntu 16.04...

CMake Error at CMakeLists.txt:22 (cmake_minimum_required): CMake 3.6 or higher is required. You are running version 3.5.1

-- Configuring incomplete, errors occurred!

lasers commented 6 years ago

Upgrade to Ubuntu 18.04 LTS, then upgrade to Conky 1.10.9_pre. :smile: Otherwise, don't worry about it. We'll leave this open for a while then. :+1:

progserega commented 6 years ago

:laughing: Okey. I will update in future... And then return to this thread.

lasers commented 6 years ago

@su8 Close this because the code no longer exist? :eagle:

su8 commented 6 years ago

Yes :rabbit:

lasers commented 6 years ago

More than 2 years, 9 months passed between 1.10.1 and current 1.11_pre (git). Code no longer exist. Closing this. Thank you for the report. :rabbit2:
