Description Flags
test program for getaddrinfo(3) none

Description Dmitry Butskoy 2011-07-26 13:31:29 UTC 
Created attachment 515280 [details]
test program for getaddrinfo(3)

Description of problem:
There is function getaddrinfo(3), which obtains and IP/IPv6 addresses by the host names. It has international (non-ascii) names support (when flag AI_IDN is used).

In Fedora 15, this function fails (but works fine at least in Fedora 12).

How reproducible:
always


Steps to Reproduce:
1. Compile the attached test program (gcc -o getaddrinfo -O2 getaddrinfo.c)
2. Run it with an "non-ascii" domain:
./getaddrinfo www.reseñas.li

Actual results:
program fails with report about malloc-related issues

Expected results:
test program should report OK


Additional info:
This bug was initially reported against traceroute (which uses getaddrinfo(3)), bug #724935
