 There are some optional features that can be enabled during compilation that are intended to help with specific types of development work or introduce experimental features. Currently, the following build options are available:
 - `ENABLE_ADDRESS_SANITIZER`: builds in runtime checks for memory corruption bugs (like buffer overflows and memory leaks) in Lagom test cases.
 - `ENABLE_MEMORY_SANITIZER`: enables runtime checks for uninitialized memory accesses in Lagom test cases.
-- `ENABLE_UNDEFINED_SANITIZER`: builds in runtime checks for [undefined behavior](https://en.wikipedia.org/wiki/Undefined_behavior) (like null pointer dereferences and signed integer overflows) in Lagom and the SerenityOS userland.

 - `UNDEFINED_BEHAVIOR_IS_FATAL`: makes all undefined behavior sanitizer errors non-recoverable. This option reduces the performance overhead of `ENABLE_UNDEFINED_SANITIZER`.
 - `ENABLE_COMPILER_EXPLORER_BUILD`: Skip building non-library entities in Lagom (this only applies to Lagom).
 - `ENABLE_FUZZERS`: builds [fuzzers](../Meta/Lagom/ReadMe.md#fuzzing) for various parts of the system.
