Help with Assertion failures

Fri, 29 May 2009 09:22:14 Z

Hello all,
I'm trying to instrument some code, which involves creation of new temporary and assigning another variableOperand as it is to the temporary, as well as adding something to that variableOperand and assigning that to the newly created temporary. The instrumentation also introduces some branches.
I'm getting the following error in the process. Can somebody please suggest or give and idea of where I might be wrong.

When (where in the phase list) are you doing instrumentation?

I was doing the instrumentation after CxxIL Reader phase.
The problem was that because my function returned a boolean, I used RegisterCondType for its return value and then used that in the compare instruction as a source. But turns out that the CompareInstruction requires sources to be of IntType.
