eh, I daily-drive a -fsanitize=address -fsanitize=undefined build of Qt and actual memory bugs are almost never a thing - I think the only time I had some were in tooling executables such as qmllint, but not in the framework itself. Most of the bugs by large are more "behaviour" bugs.

I’m impressed that QT runs clean enough under ubsan for daily use.

[jcelerier]

ubsan definitely has some warnings due to a few "technically UB" patterns used as optimizations in Qt as they are known-working on every target platform under the sun, but yeah, no crashes :)

I'm only using this configuration for the software I develop though (+ libc++ debug mode) as it's painfully slow, but it exercises the Qt codebase in depth.

Here is another bug that led to crush thatt I reported while developing my block editor:

[fransje26]

Good to know! Which version of Qt are you using?

[jcelerier]

I regularly update, right now 6.10.1 + a few patches
