            Bug ID: 21754
           Summary: crash on definition of sized operator delete
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++14
          Assignee: lvoufo at gmail.com
          Reporter: richard-llvm at metafoo.co.uk
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

This code results in an assertion in C++14 mode:

void operator delete(void*, unsigned long) __attribute__((alias("foo")));
extern "C" void foo(void*, unsigned long) {}

Failing with:

lib/CodeGen/CodeGenModule.cpp:1105: void
clang::CodeGen::CodeGenModule::EmitDeferred(): Assertion `GV ==
GetGlobalValue(getMangledName(D))' failed.
0  clang-3.6       0x0000000001f6226e llvm::sys::PrintStackTrace(_IO_FILE*) +
8  clang-3.6       0x00000000027b2b1a
