Hi Rick,
Thank you for the clarification.
Normal practice on the list is to use Reply All, so everyone can 
participate in the discussion.

It looks like most of the reports are false positives. My bikeshedding 
thought would be that it is common in Git to inspect all the call sites 
such that they don't create the various problems, rather than protect 
against the problems within the various functions, which may be a cause 
of the reports (i.e. different philosophical approach to checking).

regards

Philip

What OS version / CPPCheck version was this checked on?

In case other readers don't have a .xlsx reader here is Rick's list in 
plain text (may be white space damaged).

I expect some will be false positives, and some will just be being too 
cautious.
