I’m still looking into this, but I wanted to quickly post this
reproducer for the Guile bug:

    (use-modules (ice-9 regex))
    (define str "\U101514\U103ab0\U0f6e6e\U02e278\U01d9eb\U10b996\U1089b5\uea15\U0fa074\U101e41\U02e330\u0177\u2492")
    (match:substring (string-match "[0-8]+" str))

This triggers the out-of-range error when run with “LC_ALL=C”.
