Comment 1 Florian Weimer 2017-06-13 12:37:56 UTC 
libcrypto (with an o) is part of openssl.
Comment 2 Tomas Mraz 2017-06-13 12:45:48 UTC 
The openssl handles the SIGILL and uses it to test for the instructions present - this is not a bug.
Comment 3 Tomas Mraz 2017-06-13 12:47:43 UTC 
If you have trouble running vlc outside the gdb it is probably irrelevant to this SIGILL.
