Huw Davies (@huw) commented about dlls/localspl/provider.c:
+ HKEY hkey; + + size = sizeof(fmt_printprocessorsW) + + (wcslen(env_arch.envname) + wcslen(name)) * sizeof(WCHAR); + reg_path = malloc(size); + if (!reg_path) + return NULL; + swprintf(reg_path, size / sizeof(WCHAR), fmt_printprocessorsW, env_arch.envname); + wcscat(reg_path, name); + + status = RegOpenKeyW(HKEY_LOCAL_MACHINE, reg_path, &hkey); + free(reg_path); + if (status != ERROR_SUCCESS) + return NULL; + + if (!fpGetPrintProcessorDirectory(NULL, NULL, 1, (BYTE *)path, sizeof(path) - 1, &size)) Not that it really matters, but the `-1` looks a bit odd here, I'd suggest just passing `sizeof(path)`.
