Hi Rchard,

I have two Debian testing machine, with the same problem.


This is a fresh, qgis 2.18 build, without any flag (i use to used -
march=native), just changing the install path

So, after starting qgis, i loaded a 2.8 GB tiff image, and started to zoom in 
and out and pan, then i closed qgis:

Here is the result:

valgrind --leak-check=yes ~/FLOSS/qgis/apps_r218_no_flag/bin/qgis
