amccarth created this revision.
amccarth added a reviewer: zturner.
amccarth added a subscriber: lldb-commits.
This includes a dump file captured using Visual Studio, of the enclosed sample
program, which was also build with Visual Studio.
The tests just verify that LLDB can access some very basic information from the
mini-dump.
