--- Comment #1 from Fernando Apesteguía <fernape at FreeBSD.org> ---
Small repro:

#include <regex.h>
#include <stdio.h>

int
main()
{
        regex_t regexp;
        int ret = regcomp(&regexp, "\\s*", REG_EXTENDED | REG_ICASE |
REG_NOSUB);
        if ( ret != 0) {
                printf("regexp compilation failed: %d\n", ret);
        }

        return 0;
}

This one works in 12.2 but fails to compile the regexp in FreeBSD 14.0-CURRENT
#11 main-n245984-15221c552b3c with error 5 REG_EESCAPE   `\' applied to
unescapable character.
