It looks like you're using a Release build of LLVM. I recommend
compiling LLVM and your pass in a Debug build; that will generate
asserts and provide source line information so that you can more easily
debug the problem.
I don't have time to look at your code in detail (and chances are good
that nobody else on the list does, either), but if I had to guess,
you're probably assuming that a value is always non-NULL when it can be
NULL. I'd double check that F and other critical values are non-NULL by
adding assert statements.
