I can't reproduce this on my Debian 2.2 system running Linux
 2.2.16.  Can you give the output from "uname -a" and "dpkg 
-l libc6"?  I am using libc6 2.1.3-13.

I did a "cvs update", recompiled and ran the regtest again. Problem still persists.

Comment:
Interesting; Neil has libc6-2.1.3-13, while Lars has 2.1.3-10.  Presumably that last tag is a release level?

On the other hand, Neil is running a 2.2 Linux while Lars is running 2.0.36, and Neil also reported problems with
poll on a 2.0 machine.  So the finger of suspicion is pointing at the kernel...
