+Summary: Unmanaged code: UNKNOWN OPCODE: 51
+
+While trying to evaluate an unmanaged expression, I got this:
+
+(mdb) p src
+UNKNOWN OPCODE: 51
+ERROR: Cannot evaluate expression `src'
+
+To reproduce you need a recent libgdiplus, mono and mcs, then run this game:
+
+http://www.valil.com/netcf/GemSwap.zip
+
+It takes a while, you must drag a lot of gems, and its not obvious how the
+gems work (to me) but eventually you will get a crash, then I tried to
+evaluate the expression:
