Investigate crash on Ubuntu and other glibc Linux distros

[rdbo]

On Ubuntu and Debian, when linking against static libmem built with musl, it crashes on linux/utils.c:

if (LM_GETLINE(&stat_line, &buf_len, stat_file) > 0 && !regexec(&regex, stat_line, LM_ARRLEN(matches), matches, 0)) {
        stat_line[matches[1].rm_eo] = LM_STR('\x00'); /* place null terminator to do 'LM_STRCMP' later */
        // CRASHES IN THE LINE ABOVE!
        // GDB shows wrong values in the `matches` array
}

This no longer seems to be happening
