Isn't this already being done?
In pcre2_serialize.c a magic number (to detect endianess?), the PCRE2
version and some other info (code unit size, pointer size, PCRE2_SIZE)
are saved in the serialized data, and checked back upon loading.
Orthogonal question: is that the amount of information sufficient to
protect against decoding of trusted data, but on the wrong OS / PCRE
installation / etc.?
