+Summary: Arguments off-by-one in delegate calls from a pinvoked method
+
+If, in a non-static method, you create a delegate and call a pinvoke method
+which is supposed to call back into that delegate, the arguments are off by
+one... Presumably it is passing the instance in as the first argument, then
+the real first one as the second, etc.
+
+Attached is a test case which shows the problem.
+
+Build testlib.c something like this:
+gcc -g -o libtestlib.so -shared testlib.c
+
+and testlib.cs like so:
+mcs -o testlib.exe testlib.cs
+
+And run it.  Make sure LD_LIBRARY_PATH is set so libtestlib.so can load,
+blah blah blah.  You'll see that the expected output does not match the
+actual output and that the argument is off by one.
