ASAN errors with ref-counted strings #3

UJSON_REF_COUNTED_STRING was enabled for libstdc++ on Linux in the (outdated) BitBucket version.
With that enabled, the changes made by commit e343be1 (found by git bisect) cause ASAN errors while parsing, and thus segfaults and UB without ASAN.

The test file is canada.json from miloyip/nativejson-benchmark.

The changes to the constructor result in this ASAN log:
