../tests/test-qobject-input-visitor.c: In function ‘test_visitor_in_list’:
../tests/test-qobject-input-visitor.c:454:49: warning: ‘%d’ directive output may be truncated writing between 1 and 10 bytes into a region of size 6 [-Wformat-truncation=]
454 | snprintf(string, sizeof(string), "string%d", i);
| ^~
../tests/test-qobject-input-visitor.c:454:42: note: directive argument in the range [0, 2147483606]
454 | snprintf(string, sizeof(string), "string%d", i);
| ^~~~~~~~~~
../tests/test-qobject-input-visitor.c:454:9: note: ‘snprintf’ output between 8 and 17 bytes into a destination of size 12
454 | snprintf(string, sizeof(string), "string%d", i);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Rather than trying to be clever, since this is called 3 times during
tests, let's simply use g_strdup_printf().
