[PATCH v2 0/5] Fix scan-build warnings

From: Dominique Martinet
Date: Wed May 03 2023 - 03:49:54 EST


I ran scan-build very crudly on our source files, and there was at least
one real bug so we might as well run it once in a while, in which case
we probably ought to also fix the less important things hence this
series.
In here the first patch is a real fix and the rest is low priority, the
last one is arguably not an improvement and can be discussed (happy to
just move the 0-initializations around to variable declaration which
would also silence scan-build afaict)

Anyway, it can probably all wait until after this merge, sorry for the
timing.
