New submission from Zoltan Krajcsovics <temezs at freemail.hu>:

Command executed when the crash happened:

/usr/bin/python /usr/bin/smem -t -c command pss -P /usr/lib/chromium/chromium

The attached error.log contains the backtrace and memory map printed.

This is a sporadic error, the command is called every second 0-24, and I got one such error after half a day of running. I probably had another after a few days, but I failed to save that one, so I am not sure, if they are really the same.

It would seem that using a more overloaded / older machine triggers the error more often, the machine I got it on was a

Hewlett-Packard HP Compaq dc7900 Small Form Factor/3031h, BIOS 786G1 v01.27 10/22/2015

The problem seems to have emerged after updating to Debian Stretch.

python version:
Python 2.7.13

smem version:
(could not get an internal smem version, only the debian package)
