I think this could be already under consideration, but anyway.
I am doing FFI with libsqlite3 and want to convert an array of C strings to an array of &str:

extern fn callback(vp : *mut c_void, argc: c_int, argv : *mut*mut c_char, azColName : *mut*mut c_char){
    unsafe{
        let ar = argv as *mut[&str];
    }
}

error: internal compiler error: translating unsupported cast: *mut *mut i8 (cast_pointer) -> *mut [&str] (cast_other)
note: the compiler unexpectedly panicked. this is a bug.
note: we would appreciate a bug report: http://doc.rust-lang.org/complement-bugreport.html

[ctennis]

I'm unable to reproduce the original reported IRC using the 2015-01-08 nightly, as well as the one reporte by octplane.

The one reported by abhijeetbhagat looks to be the same as #18998.

I think this can be closed.
