<pre>While building 400 perlbench, compiler aborts with following assertion.
ld: /local/home/qa/santosh/llvm/trunk/llvm/include/llvm/Support/Casting.h:237:
typename llvm::cast_retty<X, Y*>::ret_type llvm::cast(Y*) [with X =
llvm::IntegerType; Y = llvm::Type; typename llvm::cast_retty<X, Y*>::ret_type =
llvm::IntegerType*]: Assertion `isa<X>(Val) && "cast<Ty>() argument of
incompatible type!"' failed.
Flag set - O3 flto
I think the above regression started from svn r248606</pre>
