Manfred,

I cannot confirm your problem with this specific example, but I have seen 
similar problems in other contexts and there have been other similar 
reports from time to time. It seems timing dependent and hence may be 
sensitive to all sorts of hardware details and operating conditions in any 
given system.

Perhaps running your tests under "strace" would help you home in on the 
problem?

You might also want to try your simple test case using /bin/echo instead of 
the BASH built-in "echo."
