Segmentation fault on TLS handshake

[juanparati]

I did this

curl -v https://graph.facebook.com/v12.0/act_111/

however with another sites that uses TLS it's working normally (Example: curl -v https://google.com)

I expected the following

Return normal response

I received the following

*   Trying 157.240.200.16:443...
* TCP_NODELAY set
* Connected to graph.facebook.com (157.240.200.16) port 443 (#0)
* ALPN, offering h2
* ALPN, offering http/1.1

* TLSv1.3 (IN), TLS handshake, Server hello (2):

This is the GDB output:

operating system

Linux homestead74 5.4.0-89-generic #100-Ubuntu SMP Fri Sep 24 14:29:20 UTC 2021 aarch64 aarch64 aarch64 GNU/Linux (Virtualized environment)

I tested this case with curl 7.77 on Mac OS (21.1.0 Darwin Kernel - ARM64) and also with curl 7.64.0 (Debian x86_64) and in both cases it works perfectly.

This is probably a case of a bad TLS library (version). See also #7932 (comment)
