We need to free the current_block_exits in parse_program when we're done
with it to prevent memory leaks. This fixes the following memory leak detected
when running Ruby using `RUBY_FREE_AT_EXIT=1 ruby -nc -e "break"`:
Direct leak of 32 byte(s) in 1 object(s) allocated from:
#0 0x5bd3c5bc66c8 in realloc (miniruby+0x616c8) (BuildId: ba6a96e5a060aec6fd9f05ed7e95d9627e1dbd74)
