Problem with repeated

I am trying to write a program that initializes the libwww library and
repeatedly gets pages from the Internet.  However after about 10 iterations
the requests fail.
I added a while loop to w3c-libwww-5.1m/Examples/chunk.c to show this
behaviour.  That program, BTW, calls HTRequest_new() before initializing the
library, which appears wrong but probably harmless.  I am short of time
right now and doubt I will be able to debug this problem, and am hoping for
some advice.

Also, I noticed that running

Robot/.libs/webbot -depth 1 -prefix http http://www.microsoft.com

I get, after a lot of output,

HTTPReq.c:65 Why is this?
Aborted (core dumped)

It doesn't seem like I should be on line 65 to begin with.  Can someone
check these things, to see if I have a bad libwww.a build.  I happen to be
running on a Linux system.

thank you,
