 Just by invoking `mpv` via:

 ## Python `import requests` SIGILLs
 Doing a (please note that also `python36` is affected):
 
-````
-$ python2.7 -c 'import requests'
-Illegal instruction (core dumped)
-Exit 132
-````
+    $ python2.7 -c 'import requests'
+    Illegal instruction (core dumped)
+    Exit 132
 
 leads to a SIGILL. Trying to reduce the test case this also happens with just a:
 
-````
-$ python2.7 -c 'import OpenSSL'
-Illegal instruction (core dumped)
-Exit 132
-````
+    $ python2.7 -c 'import OpenSSL'
+    Illegal instruction (core dumped)

 Trying to debug this a bit further we can see:
