Description From 2007-10-20 18:09:20
При попытке запустить VLC с интерфейсом wxwidgets на свежем Сизифе он падает с 
следущими ругательствами:

vex amd64->IR: unhandled instruction bytes: 0xF 0xF 0xC0 0x9E
==10824== valgrind: Unrecognised instruction at address 0x4EA62D2.
==10824== Your program just tried to execute an instruction that Valgrind
==10824== did not recognise.  There are two possible reasons for this.
==10824== 1. Your program has a bug and erroneously jumped to a non-code
==10824==    location.  If you are running Memcheck and you just saw a
==10824==    warning about a bad jump, it's probably your program's fault.
==10824== 2. The instruction is legitimate but Valgrind doesn't handle it,
==10824==    i.e. it's Valgrind's fault.  If you think this is the case or
==10824==    you are not sure, please let us know and we'll try to fix it.
==10824== Either way, Valgrind will now raise a SIGILL signal which will
==10824== probably kill your program.

Под валгриндом в конце концов VLC завершается вот с такими ругательствами:

GLib-ERROR **: file gmain.c: line 2064 (g_main_dispatch): assertion failed: 
(current->source == &current_source_link)

Проблема не в VLC, а в wxGTK2u, см.

Мантейнеру: просьба приложить патч

исправляющий эту проблему.
