Open requested to merge hans/sac2c:hans-address-sanitizer into develop
With this we introduce some memory leak fixes. Some were found using valgrind, other using GCC/Clang static analyses.
fixes need to be checked that don't cause issues further along the compilation stages (such as with the AST)
integrate memory leak checks into CI
integrate other checks like CWE (https://cwe.mitre.org/) stuff
