HI Libcurl

I observed below crash issue:

Usecase;
Have configured multiple threads (to divided external interfaces
logically), each has got its own multi handle (each multi handles have
curl easy handles ) which is used to post request to different host.
Initially i had only 2 threads with each having a multi handle initialized-
This was working fine.

Now we introduced a third thread in similar pattern and its getting crashed
with following dump.

Curl version;

curl 7.43.0 (x86_64-redhat-linux-gnu) libcurl/7.61.0 OpenSSL/1.1.0g

Also would like to know which is the compatible gnutls version for
libcurl Version: 7.64.0

Thanks,
