When running Kaleidoscope[1-7] from svn head (105926) in Debug mode I receive the following assertion.
Assertion failed: (C1->getType()->isIntOrIntVectorTy() && “Tried to create an integer operation on a non-integer type!”), function get, file Constants.cpp, line 1460.
Program received signal SIGABRT, Aborted.

I believe the issue is that an integer add/sub/mult/div IR instruction is being emitted when an fadd/fsub/fmul should be. I have attached a patch which fixes the assertion.
