small fixes to issues reported by analyzer

+ Currently analyzer has to be run manually with something like

	make CFLAGS='-fanalyzer -Wno-analyzer-infinite-loop'

  I use an infinite loop as an assert, I know it's not great/technically
  UB but it's just a fallback.

+ Analyzer is still somewhat limited, I could add in more
  attributes about different functions, such as memory allocation sizes
  etc.

+ If I ever set up a CI pipeline, remember to use analyzer?
