I tested this on x86_64-pc-linux-gnu with Ivo's valgrind patch from
https://bugs.kde.org/show_bug.cgi?id=345307 and it works pretty nicely.
No more spurious still reachable memory issues with memcheck.
Is there any possibility to get this backported for 5.4?
If there is anything I can do to help move this patch forward, please
let me know.
Sorry for stalling, other things distracted me. It's committed to
trunk now though.
