Hi Sami.
thank you for your answer.

Rather strange. I have up to date archlinux and the same does not
happen when I run --auto-tune.
As of today the crash is gone on my x86_64 system (all testing repos
enabled). I guess you tried on x86_64, but not i686? Don't know why
its gone in x86_64, but anyway, i686 still crashes. And the headless
server I use powertop on to elegantly optimize power settings still
crashes when using powertop --auto-tune. The funny thing is that the
settings get optimized nevertheless as a call of powertop wihout
- --auto-tune parameter shows me.
I'm just a hobbyist contributor and I haven't cracked out how
to
know where in code 'double free or corruption (!prev): 0x0975bc20'
issue happen. Could you compile the tool with debugging symbols,
and recreate issue the way we could see backtrace? That would make
fixing a lot easier.
cd /tmp wget
https://01.org/sites/default/files/downloads/powertop/powertop-2.7.tar.gz
tar xzf powertop-2.7.tar.gz
cd powertop-2.7 CXXLAGS="-O0 -g -ggdb
-fno-omit-frame-pointer"
./configure make -j3 sudo -i cd /tmp/powertop-2.7 ./src/powertop
--auto-tune [crash] coredumpctl gdb (gdb) bt full <copy paste this
output to reply>
I tried this but there was no useful output due to missing debugging
symbols, I guess what do I have to do to enable those?
Thank you
Harvey
