Bug ID: 16965
Summary: Compilation failed when using
boost::make_recursive_variant
Product: clang
Version: trunk
Hardware: PC
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: C++11
Assignee: unassignedclangbugs at nondot.org
Reporter: 191919 at gmail.com
CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
Classification: Unclassified
The following code failed to compile with clang svn trunk:
#include <map>
#include <boost/variant.hpp>
typedef boost::make_recursive_variant<
int,
std::map<std::string, boost::recursive_variant_>
>::type t_t;
typedef std::map<int, t_t> dictionary_t;
void foo(dictionary_t& d)
{
dictionary_t::const_iterator bit = d.find(42);
d[24] = bit->second;
}
The compilation command line was:
/opt/bin/clang++ -std=c++11 -stdlib=libc++ -c 1.cpp
clang++ gave the error oracle as follows:
