ASan crash during compilation
I'm using the LLVM head to build jank with ASan enabled. I ran the following configuration command:
./bin/configure -GNinja -DCMAKE_BUILD_TYPE=Debug -Djank_test=on -Djank_sanitize=address
The summary for the configuration:
-- ┌─ jank options ─────────────────────
-- │ jank build type : Debug
-- │ jank version : jank-0.1-a14789789a3888abff3b857f3a0722f40e702776

The jank compilation fails with the following error:
$ ./bin/test
