Comment 1 Florian Weimer 2017-06-13 08:37:56 EDT

libcrypto (with an o) is part of openssl.

Comment 2 Tomas Mraz 2017-06-13 08:45:48 EDT

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 08:47:43 EDT

If you have trouble running vlc outside the gdb it is probably irrelevant to this SIGILL.
