_cairo_win32_print_gdi_error (const char *context)
{
  ....
  fwprintf (stderr, L"%s: %S", context, (wchar_t *)lpMsgBuf);

}

This is what should be written: fwprintf (stderr, L"%S: %s", context, (wchar_t *)lpMsgBuf);

This suspicious code was found in Cairo project by PVS-Studio static code analyzer.
Warning message is:
V576 Incorrect format. Consider checking the third actual argument of the 'fwprintf' function. The pointer to string of wchar_t type symbols is expected. cairo-win32-surface.c 130
