DBI 1.644 cannot be compiled with gcc 14.2.1: dbih_inner()

Hello,

DBI 1.644 fails to compile with gcc 14.2.1 and perl 5.38.2:

…
DBI.xs: In function ‘dbi_ima_free’:

     ^


While the error message is ‘argument 2", the ^~~~ points to the first argument 
of hv_common_hey_len (and to the second of Perl_hv_common_key_len)

Kind regards
