[cfe-dev] clang / libc++ broken ?

[Jean-Daniel Dupas]

Hello,

I'm trying to build libc++ with the clang TOT version, but it asserts in codegen and fails.

Is it a problem on my system config (Mac OS X 10.7), or does someone else see this issue ? 

+ clang++ -c -g -Os -arch i386 -arch x86_64 -std=c++0x -U__STRICT_ANSI__ -nostdinc++ -I../include ../src/future.cpp
Assertion failed: (type->isReferenceType() == E->isGLValue() && "reference binding to unmaterialized r-value!"), function EmitCallArg, file
