Description Miroslaw Dobrzanski-Neumann 2002-02-15 18:48:54 UTC 
dlopen(..., RTLD_GLOBAL)
polutes the global namespace with symbols defined in this module
further dlopen/dlsym involves resolving started from previously loaded
modules. This way some symbols get resolved the wrong way
The correct way (as expected by the user) is using RTLD_LOCAL.
RTLD_LOCAL behaves the same way as LoadLibrary() under Windows.

Comment 2 Owen Taylor 2002-02-15 19:15:33 UTC 
Changing this is an API change, we could an extra option to load
a module without RTLD_GLOBAL
