title="RESOLVED FIXED - assertion "Result.isUninit() && "temporary created multiple times"""
href="show_bug.cgi?id=17800">bug #17800</a>.
Happens on FreeBSD with -std=c++14 (but not with -std=c++11).
The very simple program declares a boost::lockfree::queue.
I have tested with clang 3.7.0 and clang-devel (which unfortunately dates back
to 20th July 2015) with the same result.
<span class="quote">> clang++ -std=c++11 -stdlib=libc++ -lc++ -I./thirdparty/boost ./test.cpp</span >
<span class="quote">> clang++ -std=c++14 -stdlib=libc++ -lc++ -I./thirdparty/boost ./test.cpp</span >
Assertion failed: (Result.isUninit() && "temporary created multiple times"),
function createTemporary, file
/wrkdirs/usr/ports/devel/llvm37/work/llvm-3.7.0.src/tools/clang/lib/AST/ExprConstant.cpp,
line 839.
clang-3.7: error: unable to execute command: Abort trap (core dumped)
clang-3.7: error: clang frontend command failed due to signal (use -v to see
invocation)
clang version 3.7.0 (tags/RELEASE_370/final)
Target: x86_64-unknown-freebsd10.1
Thread model: posix
Repro (using Boost 1.60):
```
#include <boost/lockfree/queue.hpp>
struct message {};
static boost::lockfree::queue<message, boost::lockfree::capacity<10>>
a_message_queue;
int main() {}
