Whilst using monomerge.exe I found a case where MethodBody.Clone
didn't decode an instruction.
The method was like below:
.method assembly specialname rtspecialname instance void .ctor() cil
managed
{
.maxstack 4
L_0000: ldarg 0
L_0004: call instance void [mscorlib]System.Object::.ctor()
While processing "ldarg 0" the routine couldn't find a method
parameter to match the operand.
I have limited CIL knowledge, but I believe "ldarg 0" references the
"this" pointer.
I changed my code to recognise and clone the "this" operand.
