If no thread-specific data value is associated with key, then the value NULL shall be returned. " The glibc version pthread_getspecific(3) returns NULL for the negative key value. The musl version does not check key bounds . Is it intentional behavior?  https://git.musl-libc.org/cgit/musl/tree/src/thread/pthread_getspecific.c#n7 Thanks, Alexander.
