[vlc-devel] [PATCH] Add dummy return values to silence the?compiler warnings NO RETURN IN NON-VOID function. The compiler can't know?that this function can't reach the end (typically due to for ( ; ; ).?Arguably the compiler should see an assert(), but it keeps on warning?(openSUSE'sBuild System, and possibly others, raise this to an error due to?potentual undefined behaviour due to undefined random data being returned.
