- unused variable ‘walk’ [-Wunused-variable]
- implicit declaration of built-in function ‘free’
[-Wimplicit-function-declaration]
- initialization discards ‘const’ qualifier from pointer target type
[-Wdiscarded-qualifiers]
- variable 'ram_used' is used uninitialized whenever 'if' condition is
false [-Wsometimes-uninitialized]. This is actually easily reproducible
by specifying `memory_used_method = "XXX"`.
- comparison of integers of different signs: 'int' and 'unsigned long'
[-Wsign-compare] (for `exponent`)
