I can't see that commit, but I do see this one:

    commit d2067945159644d284f8064efbd41024f9e8448a
    Author:     Karl Williamson <khw@cpan.org>

    PATCH: [perl #130666]: Revert "toke.c, S_scan_ident(): Don't take a "end of buffer" argument, use PL_bufend"
    
    This reverts commit b5248d1e210c2a723adae8e9b7f5d17076647431.

This appears to be cause of the following compiler warning:

    toke.c:9273:41: warning: unused parameter 'send' [-Wunused-parameter]
    S_scan_ident(pTHX_ char *s, const char *send, char *dest, STRLEN destlen, I32 ck_uni)

because that commit seems have added back a 'send' parameter to
S_scan_ident(), but that function still uses PL_bufend for its actual
end-of-string delimiting.

So I'm not sure what the intent was, or how it should be fixed.
