+Summary: tramp-amd64.c assertion failure in mono
+
+Description of Problem:
+An assertion failure is tripped when running certain programs on amd64.
+I've boiled down the test case as far as I can--there doesn't seem to be
+any particular feature that stands out as a possible cause. Both source and
+binary attached.
+
+
+Steps to reproduce the problem:
+1. mcs -t:exe ArcLearn.cs -o Trampoline.exe
+2. mono Trampoline.exe
+
+Actual Results:
+$ mono Trampoline.exe 
+** ERROR **: file tramp-amd64.c: line 103 (amd64_magic_trampoline):
+assertion failed: (*vtable_slot)
+aborting...
+Killed
+
+Expected Results:
+Runs and terminates normally.
+
+How often does this happen? 
+Always, on a pretty wide range of programs, with no common pattern to the
+programs that I can figure out.
+
+Additional Information:
+Happens with this test case on latest CVS (as of 10/13); I've seen the same
+issue running 1.1.1 and earlier versions out of CVS, but run them on this
+particular test case.
