Extended Description

Compiling this with -std=c++11 (on an x86-64 system, I de-aliased uintptr_t while minimizing) crashes Clang from earlier today:

void fun() { }

void cast()
{
(void*)(unsigned long int)fun;
}

This is a regression from sometime in the last couple weeks or so. Commandline spew and such are attached.

I cannot reproduce this with 146377, which revision are you using?

I was able to reproduce this with llvm 146344 and clang 146343, so this is already fixed on trunk.
