Looks like it's fixed by removing the workarounds on the oss-fuzz side: https://github.com/google/oss-fuzz/pull/13187.

updated it to look like prev pointers. I thought of it as block heights growing but prev pointers are more accurate/less confusing.

Overall, I believe this change leaves the code in a more readable state.

I'd have used `multipath_substitutes` at the cost of being a bit more verbose but this is also fine.

Using `substitutes` seems reasonable to me as the calculated derivation path indices are indeed substituting the multipath specifier `*`.

+1 for using `placeholder`, makes it easier to follow.

(https://github.com/bitcoin-core/gui/pull/861)
This PR adds support in `CMakeLists.txt` for `-DBUILD_GUI=qt6` to allow building against system-installed Qt6 libraries in distributions that are dropping support for Qt5 (such as [Gentoo](https://bugs.gentoo.org/948836)).

I specify Qt 6.2.4 as a minimum requirement based on the work in bitcoin/bitcoin#24798, but I do not know whether Bitcoin Core currently builds against such an old version of Qt6. I have successfully built v29.0rc2 against Qt 6.8.3.

Thanks, however the changes to switch to Qt6 are being done in https://github.com/bitcoin/bitcoin/pull/30997.

(There are no plans to support both qt 5 & 6 at the same time.
