Description of problem:
When I tried to compile a very simple program to call ipv6 related
functions,including gethostbyname2, gethostbyname2_r, or getipnodebyname,
a problem happened.
You can find what i encountered in the following:

[garros@ipv6 ip6test]$ gcc -o gethostbyname2 gethostbyname2.c
gcc: Internal error: Segmentation fault (program as)
Please submit a full bug report.
See <URL:http://bugzilla.redhat.com/bugzilla/> for instructions.


For saving your effort, I have enclosed my simple progam that i tested.
In addition, I used 'gcc version 3.2 20020903' on redhat 8.0 (kernel 2.4.18-4).


How reproducible:
Always

Steps to Reproduce:
1.gcc gethostbyname2.c
