When writing some tests to my advent of code, one of the tests caused the process to exit with the message:
test tests::part2_test1 ... Process didn't exit successfully: `.../target/debug/day6-c959ab1e4c55edbf` (signal: 11)
The code that causes the error and lldb output can be found here.
The program runs fine, btw, it only fails only when running tests.
