However, this problem is only on macOS, and Valgrind doesn’t appear to run on any macOS later than 10.12 (“preliminary” support for 10.13, according to their website; I’m not sure what that means). I’m on macOS 10.15.6, and I’m using Qt 5.14.2 which has a minimum macOS version of 10.13, so Valgrind seems to be a no-go for at least one reason, perhaps two reasons (depending on “preliminary”).
There is a fork of Valgrind to support more modern macOS versions
https://github.com/LouisBrunner/valgrind-macos/
(Note: never used it myself, not a mac user).
Another option is getting a recent Clang version and rebuilding Qt and
your app with AddressSanitizer.
HTH,
