Doing some debugging in
inline size_t compareIdentifiers(const char* nullTerminated, const char* notNullTerminated, size_t length)
indicates that "nullTerminated" is the problem. notNullTerminated is "global".

Comparing a broken build with a working one shows that everyting is identical in the app-bundle except the main binary (and framework binaries).
