[LLVMdev] Add call printf instructions problems

[Tim Northover]

Hi Jin,

It's difficult to say just from looking at a pass, but one thing looked odd:

> CallInst *call_print = CallInst::Create(call_print,paramArrayRef,"",ins_temp);

This looks very dodgy. The "call_print" being used as an argument is
the (uninitialised) one that's just been declared. This could be the
source of the assertion failure (though a segfault is just as likely).

Other than that I'd suggest hooking up a debugger and going up the
call frames when that assertion hits. That should tell you exactly
which line of your pass is causing trouble.

Cheers.

Tim.
