Hi everyone,


This msg relates to an earlier one at 


http://sources.redhat.com/ml/cygwin/2004-04/msg00223.html

      
with title "Cygwin1.dll problem with Hyperthreaded machines"


I have a ASUS P4-P800E DELUXE Motherboard in my PC, with an Intel 3.2
GHz HT capable CPU.  The same symptoms as described for Cygwin 1.5.9
still show up for Cygwin 1.5.10-3, IOW:

When the machine is somewhat loaded, the simple loop like


#!/bin/bash
declare -ix ITER;
while :; do
  `let ITER=0`
  mypwd=`pwd`
  if test -z "$mypwd"; then
     echo "Test failed, mypwd is empty"
     exit 1
  else
     ITER=ITER+1
     echo "Next iteration is $ITER"
  fi
done

fails under Windows XP professional, Service Pack 1a.  Sometimes
there are about a hundred iterations, sometimes 15000, but fail it
will.


I have looked through the archives, but haven't found the
(Re-)solution.   Why is this a problem?  Large ./configure && make &&
make install jobs fail at indeterminable points in time, with the
same symptoms
