[llvm-dev] Assertion error in APInt.cpp

Hi all,
I'm experimenting with the Interpreter and all look good so far :)
Unfortunately when I play with the visitBinartOperator() method I have the
following assertion error:

Support/APInt.cpp:233: llvm::APInt llvm::APInt::operator*(const llvm::APInt
&) const: Assertion `BitWidth == RHS.BitWidth && "Bit widths must be the
same"' failed.

I have recompiled llvm and printer the 2 widths. BitWidth is 1 and
RHS.BitWidth is 32.

I would clarify that in the visitBinaryOperator() I just call
Interpreter::visitBinaryOperator(I) and I do not perform any other
operation.

Can you imagine any reason why this error happens? I have attached the file
I used for having the error.

Thanks
