error running pkg_rolling-replace

[Huub <huubvanniekerk%gmail.com@localhost>]

Hi,

After upgrading NetBSD-amd64 from 3.1 to 4.0, I'm executing 
"pkg_rolling-replace -u". Now it gives this:

> test_libdar.cpp:123: error: cast from 'void*' to 'libdar::U_I' loses precision

Can somebody please tell me how to solve this? I don't see a clear point 
of failure.

Thank you.
