Uninitialised memory detected by Valgrind after mpn_sec_tabselect on i686

I'm having some trouble with Valgrind reporting use of uninitialised memory
from code using gnutls on 32-bit x86 and I believe that I have narrowed the
problem down to the x86 asm version of mpn_sec_tabselect.
The problem goes away if I configure gmp with --disable-assembly.
If I insert VALGRIND_CHECK_MEM_IS_DEFINED(rp, n) immediately after the call
to mpn_sec_tabselect (rp, pp, n, 1 << windowsize, expbits) in mpn_sec_powm
(sec_powm.c:353) then I get:

I believe that the following simple program, when built and run against gmp
6.3.0 or r18486:f1c983debf6c on Debian 12 configured with
--host=i686-my-linux might show the same problem:
--8<--
#include <gmp.h>
#include <stdio.h>
int main()
{
mpz_t rop, base, exp, mod;
mpz_init(rop);
mpz_init(base);
mpz_init(exp);
mpz_init(mod);
mpz_set_si(base, 10);
mpz_set_si(exp, 63);
mpz_set_si(mod, 65537);
mpz_powm_sec(rop, base, exp, mod);
mpz_out_str(stdout, 10, rop);
putchar('\n');
return 0;
}

Debian 12's valgrind 3.19 also reports the same. If I insert the
same VALGRIND_CHECK_MEM_IS_DEFINED(rp, n) call immediately after the call
to mpn_sec_tabselect (rp, pp, n, 1 << windowsize, expbits) in mpn_sec_powm
(sec_powm.c:350) then I it fires:
==50688== Uninitialised byte(s) found during client check request
==50688== at 0x48AB003: __gmpn_sec_powm (sec_powm.c:350)
I do not see this problem when using Debian 12's gmp-6.2.1.
GMP version number: gmp 6.3.0 or r18486:f1c983debf6c but not Debian gmp-6.2.1
