Igor, can you run "make -k test" inside dlls/ws2_32/tests just to check if it passes in your machine? There are some tests there related to null getaddrinfo.
Passed with vanilla 1.3.33.

Created attachment 37593 [details] ws2_32: Pass NULL hostname on to native getaddrinfo.
Can you try this patch?
Tried and confirming that patch fixes issue. Thanks.
