# Known issues
## USAN, ASAN (`lz4-ubsan-x64`, `lz4-ubsan-x86`, `lz4-asan-x64`)
For now, `lz4-ubsan-*` ignores the exit code of `make usan` and `make usan32`.
Because there are several issues which may take relatively long time to resolve.
We'll fully enable it when we ensure `make usan` is ready for all commits and PRs.
See [#983](https://github.com/lz4/lz4/pull/983) for details.
## C Compilers (`lz4-c-compilers`)
- Our test doesn't use `gcc-4.5` due to installation issue of its package. (`apt-get install gcc-4.5` fails on GH-Actions VM)
- Currently, the following 32bit executable tests fail with all versions of `clang`.
- `CC=clang-X CFLAGS='-O3' make V=1 -C tests clean test-lz4c32`
- `CC=clang-X CFLAGS='-O3 -mx32' make V=1 -C tests clean test-lz4c32`
- See [#991](https://github.com/lz4/lz4/issues/991) for details.
- Currently, the following 32bit executable tests fail with `gcc-11`
- `CC=gcc-11 CFLAGS='-O3' make V=1 -C tests clean test-lz4c32`
- `CC=gcc-11 CFLAGS='-O3 -mx32' make V=1 -C tests clean test-lz4c32`
- See [#991](https://github.com/lz4/lz4/issues/991) for details.
## 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.
