  14 // This is a test for issue #3046 to make sure that when we monomorphize a
  15 // function from one crate to another the right top-level logging name is
  16 // preserved.
  17 //
  18 // It used to be the case that if logging were turned on for this crate, all
  19 // monomorphized functions from other crates had logging turned on (their
  20 // logging module names were all incorrect). This test ensures that this no
  21 // longer happens by enabling logging for *this* crate and then invoking a
  22 // function in an external crate which will panic when logging is enabled.
