I can't reproduce this, either.

It seems errno is getting clobbered somewhere after getaddrinfo
returns EAI_SYSTEM.

Can you also provide an strace? Thanks

[phasis68 (Heesob Park)]

It seems that this issue occurs on Ubuntu 13.04 and already fixed on trunk with the revision r41215

[xinjin (Sujin Phil)]

• File strace.txt strace.txt added

Seems like this behaviour only happens while running irb

r41215, r41216 and r41217 were backported to ruby_2_0_0 branch at 44900.

I can't test it on the problem platform, but I guess this will occurs with 1.9.3, too.
