 I have a problem that ghci when loads modules that uses external symbols
 incorrectly links them, the problem is not reproducible if I'm compiling
 executable or load modules with :load command.

 As a result every Pointer value is equivalent to constant
 0x0000fffffff225ff.

 A minimal example is in attached link, it contains a small package and
 description how to reproduce a bug.

 Problem is also reproduces on the ghc-HEAD.
