Comment 1 Tom Hofmann CLA 2004-12-14 11:50:21 EST 
this did not happen with I20041213-0800
Comment 2 Jerome Lanneluc CLA 2004-12-14 12:32:13 EST 
Looking at the code, it is not obvious how this can happen.
If you had steps to reproduce, that would be great.
Comment 3 Tom Hofmann CLA 2004-12-14 12:35:09 EST 
I have been running the same build on my usual workspace now, but never seen it
again.
Comment 4 Jerome Lanneluc CLA 2004-12-15 04:49:54 EST 
Thanks Tom. Please reopen if you see it again.
Comment 5 Jerome Lanneluc CLA 2004-12-15 08:59:40 EST 
Reopening as a test case was found.
