+Transmute with two differently sized types was attempted. Erroneous code
+example:
+
+```compile_fail
+fn takes_u8(_: u8) {}
+
+fn main() {
+    unsafe { takes_u8(::std::mem::transmute(0u16)); }
+    // error: transmute called with differently sized types

+Please use types with same size or use the expected type directly. Example:

+```
+fn takes_u8(_: u8) {}

+fn main() {
