Comment 1 Jerome Lanneluc CLA 2006-06-19 12:28:28 EDT 
Bad side effect of fix for bug 146615.
Comment 2 Jerome Lanneluc CLA 2006-06-19 17:09:22 EDT 
Moved code that add 'free' package fragment roots from Region#add(...) to RegionBasedTypeHierarchy constructor.

Released for 3.3M1 in HEAD and released for 3.2.1 in TARGET_321.

Verified for 3.3 M1 using build I20060807-0010.
Comment 4 David Audel CLA 2006-09-12 08:41:40 EDT
