Heob stacktraces hard to understand

[bapt]

Hello,
I'm new to qtcreator and even more for using Heob plugin. I have memory leaks on my project and i want to see where it comes from that's why I decided to use Heob (im on windows). Things are working fine but I can't understand Heob stacktraces in 'Memcheck' window (cf capture), maybe I missed something in heob's configuration, that's why i need your help :)

using: QtCreator 4.14.2/ Qt 5.12.2

(This capture shows one of the stacktrace but all are similar)

Looks like your executable is built without debug info.
And if you're using gcc, you'll need the dwarfstack dlls (there should have been a warning for this).

Also, heob can also output a flamegraph svg file (if you prefer), just add this to the Extra arguments: -vleaks.svg -g2
