ng0 pointed out this message from the curl maintainers:

"Attention! We will release a patch update within a few days to fix a
serious security problem found in curl 7.52.0. You may consider holding
off until then."

https://curl.haxx.se/download.html

So, I reverted the update for now. It seems like this new bug is more
serious than the security bug fixed in 7.52.0, CVE-2016-9586: printf
floating point buffer overflow. The other two named bugs fixed in 7.52.0
only manifest on Windows CE with the schannel TLS implementation, if I
understand correctly.
