Thanks for looking at this! It's perfectly acceptable that the pointer gets
truncated, that's unavoidable, the source that I have here uses pointer mapper
(the idea is similar to remote handle manager that msi uses), so that's not
a problem. I've created this bug report mostly for the bug with return value
being wrong, and if it's not very much effort I'd like to see it fixed.
