Was running test050 500 times. Been watching threads on test038 and 
test050 and decided to stress them on AIX as well. I am betting there is 
an intermittent pointer corruption issue that  periodically triggers a 
segmentation fault when calculating the string length. However, I was 
ill-prepared to provide the debug detail of which I knew everyone would 
be interested. :-) :-)
