commit 4568188d77815697419c8d0b2c55bcbba7f65929
Author: Pete Zaitcev <zaitcev@kotori.zaitcev.us>

    Do not discard a technical return value in tests
    
    Compilers are getting smarter, and we started getting this:
    
    libec_slap.c: In function 'test_hd_code':
    libec_slap.c:285:14: error: 'frags.array' may be used uninitialized
     in this function [-Werror=maybe-uninitialized]
    
    The fix is to consume the error code in such a way that the
    test proceeds further only when frags are indeed initialized.
