[PATCH 00/22] Memory leak fixes (pt.4)

[Patrick Steinhardt <ps@pks.im>]

[-- Attachment #1: Type: text/plain, Size: 4615 bytes --]

Hi,

the third set of memory leak fixes was merged to `next`, so this is the
next part of more or less random memory leak fixes all over the place.
With this series, we're at ~155 leaking test suites. Naturally, I've
already got v5 in the pipeline, which brings us down to ~120.

The series is built on top of 406f326d27 (The second batch, 2024-08-01)
with ps/leakfixes-part-3 at f30bfafcd4 (commit-reach: fix trivial memory
leak when computing reachability, 2024-08-01) merged into it.

Thanks!

Patrick
