[asterisk-users] Asterisk SSL support broken with update from openssl-1.0.0 to 1.0.1e, recompiling does *not* help

[Alex Villací­s Lasso]

I am having an issue that prevents WebSockets over SSL/TLS (or any kind of encrypted HTTP traffic to Asterisk) from working after an openssl library update.

My setup is CentOS 6 x86_64, and initially, with openssl[-devel]-1.0.0-20.el6_2.5.x86_64 . With this openssl versions, https over TCP port 8089 initializes correctly with asterisk-11.7.0. After an upgrade to openssl[-devel]-1.0.1e-16.el6_5.4.x86_64 , I 
compiled asterisk-11.8.1 . When testing the exact same configuration, I noticed that TCP port 8089 was no longer listening, even though TCP port 8088 (standard unencrypted HTTP) was. After a patch coaxing some error message to be shown in the logs, I got 
the following:

 From googling around, I see that reason(161) means that somehow, there are no loaded cyphers for SSL (source: http://marc.info/?l=openssl-users&m=99129794725716&w=2). This source also claims that the most common cause is that SSL_library_init() was not 
called. However, I do not see anything in the Asterisk changelog that could possibly cause the call to be skipped.

I see nothing out of the ordinary when configuring Asterisk using the updated openssl:

What else could I check? I have checked issues.asterisk.org and there is no mention of a situation similar to mine, so I believe this is somehow related to the build environment.
