Error compiling 1.4.6 with gcc -ftracer

Can't compile xkbcomp-1.4.6 due to an array-bounds error:

geometry.c:2580:9: error: ‘strncpy’ offset [0, 3] is out of the bounds [0, 0] [-Werror=array-bounds]
 2580 |         strncpy(key->over, keyDef->over, XkbKeyNameLength);
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
geometry.c:2581:9: error: ‘strncpy’ offset [0, 3] is out of the bounds [0, 0] [-Werror=array-bounds]
 2581 |         strncpy(key->under, keyDef->under, XkbKeyNameLength);
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The command line used is:

./configure --prefix=/usr --sysconfdir=/etc --mandir=/usr/share/man \
  --localstatedir=/var --disable-dependency-tracking
make

Also tried adding the --disable-strict-compilation option with the same result.

gcc version 12.2.0 (GCC)
