```
compiler: avoid use of undefined memory

InternPool is nice in some ways but it also comes with its own set of
footguns. This commit fixes 5 instances. I see quite a few Valgrind
warnings remaining when running the behavior tests.

Perhaps the solution is to have stringToSlice return a struct with start
and length as indexes, which has a format function?
