#442: Reloading .so files
---------------------+------------------------------------------------------
 Reporter:  mario    |       Owner:       
     Type:  defect   |      Status:  new  
 Priority:  major    |   Milestone:  4.7.0
Component:  unknown  |     Version:  4.6.x

 It seems that .so files cannot be properly reloaded when the loader is
 compiled.

 Below you can see the steps to reproduce the problem.

 Christian said he cannot reproduce the problem with 4.6.3 on macos.

 I tried it on Linux with 4.4.0, 4.6.3 (dev-snapshot tarball) and
 c157ff502829c6f2856df4a963d81a88ee241ebf (experimental).
