[0/2] ci: detect more warnings via `-Og`

Hi,

this patch series is triggered by the thread at [1], where Peff noted a
potentially-uninitialized variable. In theory, GCC is able to diagnose
such issues via `-Wmaybe-uninitialized`. But in practice, this warning
is dependent on the optimization level used by GCC, where the issue in
the thread is only noticed when compiling with `-Og`.

The first patch is just a small fix to our CI I found while at it. The
second patch adapts our "pedantic" job to compile with `-Og` so that we
overall surface more issues. This would've catched the issue.
