I've backported the patch to gdb 12.1 and verified that the assert doesn't
trigger anymore.

I've also looked at all the test-cases containing the assert:
- gdb.base/callfuncs.exp
- gdb.base/infcall-nested-structs-c++.exp
- gdb.base/infcall-nested-structs-c.exp
- gdb.base/structs.exp
- gdb.base/varargs.exp

All of them pass without fails, except for varargs.exp, which has:
...
(gdb) print find_max_long_double_real(4, ldc1, ldc2, ldc3, ldc4)^M
$8 =3D 0 + 0i^M
(gdb) FAIL: gdb.base/varargs.exp: print find_max_long_double_real(4, ldc1,
ldc2, ldc3, ldc4)
...
while this is expected:
...
$8 =3D 4 + 4i^M
...

Unfortunately, I don't have access to a machine atm to investigate this.
