<pre>
    From the clang testsuite, file ./Analysis/analysis-after-multiple-dtors.cpp
does this with a valgrind version of recent clang:

test $ valgrind -q --trace-children=yes ~/llvm/results/bin/clang++   -c -w ./Analysis/analysis-after-multiple-dtors.cpp
==424675== Conditional jump or move depends on uninitialised value(s)
==424675==    at 0x2429FF9: clang::CodeGen::CodeGenModule::SetLLVMFunctionAttributesForDefinition(clang::Decl const*, llvm::Function*) (CodeGenModule.cpp:2531)
==424675==    by 0x26F5B23: clang::CodeGen::CodeGenModule::codegenCXXStructor(clang::GlobalDecl) (CGCXX.cpp:216)

The source code line in error is

    if (isa<CXXMethodDecl>(D) && F->getPointerAlignment(getDataLayout()) < 2)

The bug first seems to occur sometime between git hash 1579e9ca9ce17364963861517fecf13b00fe4d8a and 83646590afe222cfdd792514854549077e17b005.
