           Summary: error cs1502 reported in mono-tools/Mono.Profiler
                    build

/ObjectModel.cs(1674,31): error CS1502: The best overloaded method match for
`System.Array.Sort(System.Array, System.Array)' has some invalid arguments
/home/mkestner/INSTALL/lib/mono/2.0/mscorlib.dll (Location of the symbol
related to previous error)
/ObjectModel.cs(1674,31): error CS1503: Argument `#2' cannot convert
`System.Comparison<Mono.Profiler.HeapItemSetStatisticsBySubject<HISSS>>'
expression to type `System.Array'
Compilation failed: 2 error(s), 0 warnings

The offending code is:

                        Array.Sort (result,
HeapItemSetStatisticsBySubject<HISSS>.CompareByAllocatedBytes);


The static field referenced in param 2 is defined as:

        public abstract class HeapItemSetStatisticsBySubject<HISSS> :
IHeapItemSetStatisticsBySubject where HISSS : IHeapItemSetStatisticsSubject {

                public static Comparison<HeapItemSetStatisticsBySubject<HISSS>>
CompareByAllocatedBytes = delegate (HeapItemSetStatisticsBySubject<HISSS> a,
HeapItemSetStatisticsBySubject<HISSS> b) {
                        return a.AllocatedBytes.CompareTo (b.AllocatedBytes);
                };

This worked with my previous bootstrap from 6/19 from trunk, but breaks on a
curent bootstrap of mcs r138326.
