How often does this happen?
For all non-trivial test cases.
I can provide a core dump, if it helps. It's about 15 Mb in size.

+The assert is now fixed in SVN, but the tests still don't run, cause
+they expose another, much harder to fix bug. The problem is with the
+ldftn IL instruction and delegates. On MS.NET, it is permitted to
+pass a method declared in an interface (an abstract method) to ldftn.
+When the result of ldftn is passed to a delegate ctor, they seem to
+lookup the method in the delegate target, much like ldvirtftn. We
+don't do this, so when the delegate is called, we try to compile the
+abstract method, leading to a crash inside the JIT.
