The CommandObjectThread m_step_count variable is current set as int32_t but when it's assigned, and when it's compared to other things, it's used as a uint32_t. This CL changes the type to match the usage.
lgtm, I will commit both of these for you.
In the future specify some value for -U large enough to generate enough context to see the whole file. Like -U999999. Otherwise I have to go look at the source on disk to see all the places where this variable is used and make sure everything looks ok.
