Local fix
n/a
Problem summary
Blue Gene L and P users are affected by this issue. Incorrect floating point results lead to incorrect result values from functions.
Problem conclusion
The compiler has been fixed by repairing the way we remove an item from an array so that we correctly update the links associated with the array.
