Broken Code Sample
Creating a default-constructed std::pair stack-dumps in the following way:
clang: /home/mordred/src/llvm/tools/clang/lib/CodeGen/CGExpr.cpp:605:
llvm::Value* clang::CodeGen::CodeGenFunction::EmitToMemory(llvm::Value*,
clang::QualType): Assertion `Value->getType()->isIntegerTy(1) && "value rep of
bool not i1"' failed.
Stack dump:
0. Program arguments: /usr/local/clang/bin/clang -cc1 -triple
x86_64-unknown-linux-gnu -S -disable-free -main-file-name foo.cc
-mrelocation-model static -mdisable-fp-elim -mconstructor-aliases
-munwind-tables -target-cpu x86-64 -resource-dir

-fcolor-diagnostics -o /tmp/cc-0YJ9sv.s -x c++ foo.cc
1. <eof> parser at end of file
2. Per-file LLVM IR generation
3. /usr/include/c++/4.4/bits/stl_pair.h:79:7: Generating code for
declaration 'std::pair<std::_Rb_tree_iterator<std::pair<const
std::basic_string<char>, Foo *> >, bool>::pair'
clang: error: clang frontend command failed due to signal 6 (use -v to see
invocation)
With the attached foo-broken.cc on latest trunk. If I change it to
foo-fixed.cc, it works.
