SUMMARY
Valgrind crashes while checking a program (a C compiler) that is known to be
faulty.
STEPS TO REPRODUCE
1. Decompress the provided attachment
2. Run `valgrind ./build/main/lilycc test-files/test_compound.c`
OBSERVED RESULT
Valgrind detects an invalid read and an invalid write, then receives a
segmentation fault in its own code.
EXPECTED RESULT
Valgrind itself should not have received the segmentation fault.
