Flawfinder version 2.0.10, (C) 2001-2019 David A. Wheeler. Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/ocaml-gavl-0.1.6/src/gavl_stubs.c FINAL RESULTS: data/ocaml-gavl-0.1.6/src/gavl_stubs.c:39:8: [1] (free) memalign: On some systems (though not Linux-based systems) an attempt to free() results from memalign() may fail. This may, on a few systems, be exploitable. Also note that memalign() may not check that the boundary parameter is correct (CWE-676). Use posix_memalign instead (defined in POSIX's 1003.1d). Don't switch to valloc(); it is marked as obsolete in BSD 4.3, as legacy in SUSv2, and is no longer defined in SUSv3. In some cases, malloc()'s alignment may be sufficient. void * memalign (size_t align, size_t size); data/ocaml-gavl-0.1.6/src/gavl_stubs.c:42:9: [1] (free) memalign: On some systems (though not Linux-based systems) an attempt to free() results from memalign() may fail.
