Summary: GCHandle.AddrOfPinnedObject gives incorrect address for arrays
Original Submission: When a GCHandle with GCHandleType.Pinned is created, it
should be possible to obtain the address of the object with
GCHandle.AddrOfPinnedObject(). When the object in question is an array, Pnet
appears to return a pointer to some header information that preceeds the actual
appear data. However, Rotor returns a pointer to the first element of the
array. Note in the output samples below that element 1 is incorrect and that
the array indexes are offset.
To compile the test cases, use
1. gcc -shared -o libtest.so test.c
2. cscc -o test.exe test.cs
3. ilrun test.exe
Output from ilrun:
136372232 136372232
size of array[x]: 1
==> array(1) = 48
==> array(1986) = 1
==> array(1987) = 2
Output from Rotor:
1093363496 1093363496
size of array[x]: 1
==> array(1982) = 1
==> array(1983) = 2
