 Bitcoin Core can be compiled with various "sanitizers" enabled, which add
 instrumentation for issues regarding things like memory safety, thread race
 conditions, or undefined behavior. This is controlled with the

 sanitizers to enable. The sanitizer list should correspond to supported
 `-fsanitize=` options in your compiler. These sanitizers have runtime overhead,
 so they are most useful when testing changes or producing debugging builds.

 Not all sanitizer options can be enabled at the same time, e.g. trying to build

 these sanitizers are mutually incompatible. Refer to your compiler manual to
 learn more about these options and which sanitizers are supported by your
 compiler.
