As you wrote:

...
fprintf (stderr, "rv = %p, r = %p, r->per_dir_config = %p, "
		 "r->server->module_config = %p\n", 
		 rv, r, r->per_dir_config, r->server->module_config);
config = *(value *) ap_get_module_config (r->per_dir_config, &caml_module);
fprintf (stderr, "ap_get_module_config done\n");
...

then the error_log contains:
rv = 0x403b74cc, r = 0x80f5924, r->per_dir_config = (nil),
r->server->module_config = 0x80b20e4
