# Runtime sanitizers
## Using sanitizers in this project
All debug builds are by default built with address and undefined runtime
sanitizers. To disable them (which is strongly discouraged) run cmake with
options none.
```shell
cmake -DSANITIZERS=none
```
To run other selection of sanitiser use, pass colon separated list to the
command.
```shell
cmake -DSANITIZERS=memory,undefined
```
NOTE: Some sanitizer cannot be used together, like address and memory.
### Sanitizer debug info and Clang
If you are using sanitizers with clang and you don't files and line numbers,
make sure that `llvm-symbolizer` is installed and if that does not help, add
env `ASAN_SYMBOLIZER_PATH=` with path to your symbolizer executable. Most of the
time, having it in `PATH` should be enough.
