[cfe-dev] [clang-3.2] unique_ptr: compiler errors

[Suman Kar]

Hello,

The following:

#include <memory>
int main() {
 using namespace std;
 unique_ptr<int> up( new int( 30 ) );
}

generates:

$ /d/llvm_workspace/build/Debug+Asserts/bin/clang++ -std=c++11 -Wall foo.cpp
 -o foo

I am using clang 3.2 version:

clang version 3.2 (trunk 157115) (llvm/trunk 157155)
Target: i686-pc-mingw32
Thread model: posix

I'd like to know if this is a problem with my installation/gcc/build
issue. Any help will be much appreciated.

Regards,
Suman
