I prepared an update for the curl package with the two upstream patches applied
(38d8e1b and 4015fae), and uploaded the result for amd64 at:
https://people.debian.org/~ghedo/libcurl4_7.64.0-3_amd64.deb

Guillem, could you try this version of the package and see if it fixes the
issue for you? Once that's confirmed I'll upload to sid and ask for unblock.

Cheers
