I don't really see anything obviously wrong. But I'm not sure what you
are expecting. This is going to just build the top commit in branch
master, and if the commit hash has changed it will remove any previous
results for that commit before starting the build. So you will always
get a full list of errors, not a delta from last time. If you want
that you could add a second commit with your fixes and not adjust the
first commit in the branch (and use -c2).

If you leave off '-b master -c1' it would have about the same effect,
assuming that you have 'master' checked out.

In the second line you are specifying -ve twice but that doesn't
matter. Why are you changing the thread/jobs defaults? Does that speed
it up? Also you don't need the quotes and the | between archs.

Also note there is --step to avoid building every commit. For example,
this will build the upstream commit and your branch's top commit
(only) assuming that master tracks upstream/master.

buildman -b master --step 0

Simon
