Known issues

USAN, ASAN (lz4-ubsan-x64, lz4-ubsan-x86, lz4-asan-x64)

For now, lz4-ubsan-* uses the -fsanitize-recover=pointer-overflow flag: there are known cases of pointer overflow arithmetic within lz4.c fast compression. These cases are not dangerous with known architecture, but they are not guaranteed to work by the C standard, which means that, in some future, some new architecture or some new compiler may decide to do something funny that could break this behavior. Hence, in anticipation, it's better to remove them. This has been already achieved in lz4hc.c. However, the same attempt in lz4.c resulted in massive speed losses, which is not an acceptable cost for preemptively solving a “potential future” problem not active anywhere today. Therefore, a more acceptable work-around will have to be found first.

cppcheck (lz4-cppcheck)

This test script ignores the exit code of make cppcheck. Because this project doesn't 100% follow their recommendation. Also sometimes it reports false positives.
