Comment (by jyavenard):
Sorry, I made a mistake associating the commit ba354a8c ; that one
introduced the https issue.
Git bisect find that this is the culprit for the regression. I'm not 100%
sure that it is completely the problem as git bisect often acts weird when
working through merge with remote forks

commit 3bdb438e6517ec342e93298de571688584050d68

http: Add support for using persistent connections
Add a new AVOption 'multiple_requests', which indicates if we want
to use persistent connections (ie. Connection: keep-alive).

reverting that commit gives me bus error but no av_free error. As such,
I'm not convinced that the problem can be entirely attributed to this
